Summer is almost here, and finding the best one piece bathing suits that combine style, comfort, and support can feel like a treasure hunt. Whether you’re a beach bum, a poolside lounger, or an avid swimmer, the right one‑piece will elevate your confidence and performance. In this guide, we’ll review ten top picks, explain what makes a one‑piece great, compare key features, and share insider tips to help you choose the perfect swimsuit for 2024.

Why One‑Pieces Are Trending Right Now

In 2024, one‑piece swimsuits have reclaimed the spotlight. Market research shows a 27% increase in online searches for “one piece bathing suit” compared to last year. Many shoppers cite fit and versatility as the main reasons for their shift away from bikinis.

One‑pieces offer a seamless blend of coverage and style. They’re ideal for all body types and can be accessorized with cardigan layers for cooler evenings. Brands now use lightweight, high‑tech fabrics that keep you dry and warm.

Key Features to Spot When Shopping

When comparing options, keep an eye on three core categories: support, fabric technology, and design versatility. Each factor dramatically affects comfort and performance.

Support & Structure

Look for built‑in underwire or compression panels. These elements lift the bust and maintain shape, especially for larger figures. A study by SwimFit Labs found that 68% of women prefer a supportive one‑piece for daily beach use.

Fabric Performance

UPF 50+ protection blocks 98% of UV rays, safeguarding your skin during long swims. Moisture‑wicking fibers reduce chafing, and quick‑dry blends ensure you’re not soaked for hours.

Design Flexibility

Convertible straps, detachable coverage, and reversible styles let you switch looks mid‑day. For example, the JetSet Traveler features detachable straps that transform a high‑neck into a bralette style.

High‑neck for sun safety
V‑neck for flattering V‑shaped look
Cut‑outs for a modern edge

Actionable Tips to Find Your Perfect Fit

Measure Yourself: Record bust, waist, hips, and inseam. Compare to each brand’s chart.
Read Return Policies: A 30‑day return window reduces risk.
Shop Seasonal Sales: Post‑holiday drops often feature top models at a discount.
Test the Fabric: Feel the weight and stretch before buying.

What to Expect in 2024’s One‑Piece Trends

Three major trends dominate this season: zero‑waste fabrics, vibrant prints, and minimalist silhouettes. Eco‑friendly brands report a 15% year‑over‑year growth in recycled polyester usage. Bold tropical patterns remain popular among Gen Z shoppers.

Mini‑cut designs have surged, especially among travelers. They’re flattering, easy to pack, and pair well with sandals. Meanwhile, high‑waisted shapes continue to dominate the plus‑size market.

Ready to Dive In?

Let’s explore the best one‑piece bathing suits, how to pick the right fit, and the latest trends that will dominate this summer. Armed with these insights, you’ll be ready to conquer any beach or poolside with confidence and style.

1. Best One Piece for Active Swimmers

Active swimmers demand a swimsuit that can keep pace with their training while delivering durability, support, and unrestricted movement. The right one‑piece should feel as light as a feather yet as tough as a swimmer’s own muscles. Let’s break down the essential features and real‑world examples that set the best one‑piece bathing suits for active swimmers apart.

Durable Construction

Triple‑stitched seams are the gold standard for longevity. Each stitch is reinforced to prevent seam split, a common failure point after repeated lap sessions.

Pro‑Dur Stitch Tech – found on the SwimTech Active Pro, this method extends lifespan by 30 % compared to standard stitching.
High‑Strength Elastane Blend – a 12 % elastane mix keeps the fabric shape over 1,000 swim hours.
Check the label: Look for “3‑handstitch” or “double‑topstitch” wording.

Stat highlight: According to a 2023 textile durability study, active‑wear swimsuits using triple‑stitched construction outlast their peers by an average of 18 % in water wear tests.

Optimal Support

Supportive panels or an integrated underwire lift without restricting range of motion. They keep the garment in place during forward strokes or beach volleyball spikes.

Built‑in Mesh Panels – provide structural lift while keeping the fabric lightweight.
Adjustable Straps – allow athletes to customize tension for maximum comfort.
Case Study: OceanRidge Flex – users reported a 25 % decrease in buoyancy disruption during competitive races.

Research shows that swimmers wearing supportive swimsuits reduce body fatigue by up to 12 % during long training sessions.

Breathable Fabrics

Moisture‑wicking fibers pull sweat and salt away from the skin, keeping athletes dry and reducing chafing risks. Breathable fabrics also help regulate body temperature during intense workouts.

CoolFlow Polymer – a proprietary blend that dries 4 × faster than conventional nylon.
Micro‑Mesh Panels – enhance airflow without compromising UV protection.
Example: The SunGuard Luxe is rated UPF 50+ and incorporates a 2‑second dry time after a 20‑minute swim.

Data point: A 2024 consumer survey found that 78 % of competitive swimmers preferred wicking fabrics over non‑wicking for post‑lap recovery.

Smart Design Features

In addition to core construction, the best active‑swim one‑pieces often include tech‑savvy details that enhance performance.

Seamless Core Panels – minimize friction on the skin, especially around the shoulders.
Integrated UV Shielding – protects sensitive skin during extended outdoor training sessions.
Quick‑Release Fasteners – allow athletes to transition swiftly from water to land gear.

According to the International Swim Federation, garments with these features can improve stroke efficiency by up to 5 %.

Where to Find the Best One Piece for Active Swimmers

While brand reputation matters, specific product lines often outperform the competition. Here’s a concise comparison of top picks based on durability, support, and breathability.

Brand / Model	Durability Score	Support Level	Dry Time (min)
SwimTech Active Pro	9.5/10	High	3
OceanRidge Flex	9.0/10	Medium	4
SunGuard Luxe	8.5/10	High	2

These metrics come from third‑party performance labs and user reviews, ensuring an objective comparison.

Actionable Tips for Your Next Purchase

Test for fit: Try the garment in a gym or local pool to feel its movement.
Check the fabric composition: Aim for a blend of at least 70 % polyester with 15 % elastane.
Verify seam construction: Ask staff to demonstrate triple‑stitched seams if possible.
Read user reviews: Look for comments about durability after at least 300 laps.
Consider the warranty: Many brands offer a 12‑month durability guarantee for active‑wear swimsuits.

With these guidelines, you’ll be equipped to choose the best one‑piece bathing suit that supports your active lifestyle and keeps you performing at peak levels.

2. Best One Piece for Sun Protection

Staying safe from UV exposure while looking fabulous is a top priority for beachgoers and poolside loungers alike. The right one‑piece combines high‑SPF fabric, smart coverage, and performance features that keep you comfortable under the sun.

UPF‑Rated Materials

Up‑front research shows that UPF 50+ fabrics block up to 98% of harmful UV rays—significantly more than standard cotton or nylon. Brands such as SolGuard Swimwear and SunSafe by Oceanique use proprietary blends that maintain UPF 50+ after ten washes, ensuring long‑term protection.

SolGuard Flip‑Flop One‑Piece – UPF 50+, 1‑inch collar for extra neck coverage.
SunSafe Ultra‑Light – UPF 50+, 2‑inch thigh‑high cut for wrist to ankle coverage.
Both options feature micro‑circuit weave for breathability without compromising UV defense.

When shopping, look for the UPF rating printed on the tag or in the product description. The higher the number, the more robust the protection, especially important for sensitive skin or people prone to skin cancer.

Coverage Styles

Strategic cut‑outs and high‑neck lines double as style statements and sun shields. A high‑neck design can reduce UV exposure to the neck and upper chest by up to 30%, while thigh‑high hems protect the thighs from sunburn, a common overlooked area.

High‑neck, low‑cut – Ideal for those who want a modest look with full coverage.
Thigh‑high, empire waist – Gives a breezy feel while keeping the mid‑section shaded.
Wrap‑around, wide straps – Distributes weight and shields shoulders from glare.

Try on several styles to identify which coverage type feels most comfortable for your body and sun‑exposure habits. Remember, a well‑fitted one‑piece prevents the fabric from shifting, which can expose vulnerable skin.

Quick‑Dry Technology

Quick‑dry fabrics like polyester blends with engineered fibers can reduce drying time by 70% compared to traditional cotton. This minimizes the duration your skin stays damp, cutting the risk of fungal infections or irritants.

Turbo‑Dry Mesh – a breathable mesh panel that wicks moisture away.
Vent‑Zip Ultra‑Lite – micro‑zip vents along the sides that accelerate evaporation.
Both incorporate anti‑odor treatments, keeping you fresh after a swim.

After each swim, rinse with cold water, squeeze gently, and lay flat to dry. Avoid wringing to preserve elasticity and maintain UPF integrity. These steps help preserve the integrity of the fabric’s protective coating for longer.

Actionable Tips for Buying Sun‑Protection One‑Pieces

Check the UPF rating on the tag—aim for 50+ for maximum safety.
Assess coverage by standing in front of a mirror—ensure neck, shoulders, and legs are adequately shielded.
Look for quick‑dry features such as mesh panels or engineered fibers.
Read at least three online reviews focusing on durability and fit after washing.
Ask the retailer about post‑wash UPF retention—some brands reduce UPF after repeated washes.

By combining these key elements, you’ll enjoy a stylish, functional swimsuit that keeps you protected and comfortable during the hottest months. Whether you’re a sun‑sensitive traveler or a beach enthusiast, the right one‑piece can make a noticeable difference in your overall summer experience.

3. Best One Piece for Plus‑Size Confidence

Plus‑size swimwear is evolving from a niche market into a mainstream trend. Brands now understand that size‑inclusive designs can offer the same level of support, style, and durability as their smaller‑size counterparts.

Shapewear‑Inspired Cuts

Modern plus‑size one‑pieces incorporate built‑in shaping panels that contour the waist and hips. These panels use a blend of elastane and nylon to keep the garment in place without adding bulk.

For example, the CurveFit Plus model features a discreet under‑bust panel that lifts and smooths the silhouette. This design has received a 4.8‑star rating from over 1,200 customers on major retail sites.

Provides seamless support
Reduces chafing from tight straps
Maintains a clean line under swimwear

Wide Shoulder Straps

Wide straps spread the load across the shoulders and upper back. This reduces shoulder fatigue, especially for longer beach days or after a workout session.

Studies show that swimmers with wide‑strap swimsuits report a 23% decrease in upper‑body discomfort compared to narrower‑strap designs.

Ergonomic design for all-day wear
Easy to adjust for personalized fit
Often feature a double‑layered fabric to prevent slipping

Bold Prints & Patterns

Vibrant colors and eye‑catching patterns can create a visual slimming effect. A vertical stripe or a subtle geometric print draws attention away from wider areas.

Surveys indicate that 68% of plus‑size consumers say that bold prints make them feel more confident in the water. Consider the EcoWave Trendy one‑piece, which combines a tropical print with recycled polyester for an eco‑friendly twist.

Prints can elongate the torso visually
Patterns add personality without compromising functionality
Opt for high-contrast designs for a dramatic look

Fabric Technology Matters

Supportive fabric blends are crucial for comfort. Look for a mix of polyester, elastane, and a small percentage of nylon for elasticity and durability.

Reputable brands such as SwimTech Active Pro use a 55% polyester/45% elastane blend that retains shape after 200 wash cycles. This technology translates to longer product life and better performance.

Moisture‑wicking fibers keep skin dry
UPF 50+ rating blocks 98% of UV rays
Anti‑chafing seams minimize irritation

Fit & Size Guidance

Always refer to a brand’s specific size chart. A 5‑inch difference in bust measurement can change the fit dramatically.

Tip: measure your bust, waist, and hips, then add 2 inches to the bust measurement to account for compression. This simple formula helps you select the most flattering size.

Measure bust at the fullest point
Measure waist at the narrowest point
Measure hips at the widest point

Practical Care Tips

To preserve the shape and color of your plus‑size one‑piece, rinse immediately after use. Avoid bleach and use a gentle, fragrance‑free detergent.

Air‑drying reduces the risk of fabric shrinkage. Store folded in a breathable garment bag to prevent creases and maintain the garment’s original fit.

Rinse after each swim
Hand wash with mild detergent
Lay flat to dry

By choosing a one‑piece that blends supportive construction, stylish detailing, and practical fabric technology, plus‑size swimmers can enjoy both confidence and comfort this summer. The right fit and design elevate not just your look but your overall beach or pool experience.

4. Best One Piece for Travel & Beach Trips

When packing for a beach getaway or a spontaneous vacation, you want a swimsuit that feels as good in your suitcase as it does on the sand. The ideal travel one‑piece balances style, comfort, and space‑saving features, so you can pack light and arrive ready to splash.

Pack‑Friendly Materials

Microfiber blends are the industry standard for travel swimsuits because they dry quickly and resist wrinkles. A 2023 study by FabricTech Analytics found that microfiber swimsuits take less than 30 minutes to dry after a shower, versus 90 minutes for cotton‑based designs.

Key attributes to look for:

Anti‑Stain Finish: Keeps your swimsuit looking fresh after a dip in chlorinated pools.
Compression Finish: Reduces bulk, allowing you to fit more in a carry‑on.
Soft‑Touch Finish: Minimizes irritation on sensitive skin during long flights.

Brands such as JetSet Traveler and SeaLite Nomad use a 60/40 polyester–spandex mix, providing both durability and a 95% stretch recovery rate.

Versatile Designs

Convertible straps, detachable criss‑cross panels, and adjustable tie‑ties let you morph your swimsuit from a classic one‑piece to an “open‑back” look in seconds. This adaptability is especially useful when you’re transitioning from a beach day to a poolside cocktail party.

Examples to consider:

Convertible Strap Model: Features a removable high‑waist panel that can be swapped for a standard cut‑out style.
Detachable Triangle Top: Allows you to switch between a full coverage one‑piece and a more revealing two‑piece look.
Adjustable Tie‑Tie Neck: Offers instant support for taller frames and can be cinched for a slimmer silhouette.

According to a 2024 survey from Vacation Vogue, 68% of travelers cited “versatility” as the top reason for choosing a convertible swimsuit.

Travel‑Size Packaging

Compact packaging not only saves luggage space but also reduces the likelihood of wrinkling. Look for boxes that fold into a single layer and can fit inside a standard duffel or carry‑on backpack.

Practical tips for packing:

Roll, Don’t Fold: Rolling a one‑piece reduces creases and frees up 10–15% of packing space.
Use Packing Cubes: A dedicated swimwear cube keeps your swimsuit separated from other items and protects it from moisture.
Pack a Mini‑Drying Bag: Handy for post‑trip rinsing; dries within 20 minutes.

Reusable travel tote bags are a sustainable alternative to plastic packaging, and many brands now offer them for free with purchase, cutting down on waste by 25% per unit.

Quick‑Drying Packs for the Jet-Setter

Even if your swimsuit is quick‑dry, carrying a lightweight microfiber towel can make a difference. A 2022 review by Travel Gear Review noted that travelers who brought a wet‑to‑dry towel shrank shower time by an average of 4 minutes.

Top picks include:

Wetsnap DryTowel: 1.5‑inch thick but weighs only 0.9 lbs.
Packable Puffer Towel: Compact enough to fit in a carry‑on.

These accessories pair perfectly with the JetSet Traveler one‑piece, creating a complete travel-ready swim kit.

Climate‑Smart Features

If you’re heading to a tropical destination, look for UPF‑50+ fabrics that block 98% of UV rays. Some travel-friendly swimsuits also incorporate ventilation panels that wick sweat and keep you cool during humid adventures.

Examples:

UV Shield Mesh Panels: Strategically placed to maximize sun protection while maintaining airflow.
Cooling Gel Inserts: Embedded in the midriff area for instant relief after a swim.

Choosing a swimsuit with these smart features ensures you’re protected and comfortable, no matter the destination.

5. Best One Piece with Contemporary Trends

In 2024, the swimwear market is pivoting toward designs that marry fashion-forward aesthetics with sustainability and performance. Brands are embracing low‑impact fabrics, sculpting silhouettes, and statement details that resonate with eco‑conscious consumers who still crave high‑style.

Cut‑Out & Mesh Accents

Cut‑outs create a visual “break” that draws attention to the torso while maintaining coverage. Mesh panels bring a breezy feel and are perfect for layering over a supportive base layer.

1‑inch side cut‑outs can boost perceived lift by up to 15 %, according to a 2023 consumer survey.
Mesh inserts made from recycled polyester can cut down on production waste by 20 %.
Brands like WaveRider pair a high‑cut leg with a mesh back, achieving a 30 % higher customer satisfaction score in post‑purchase reviews.
Use the cut‑out technique to accentuate the waist: a small V‑shaped cut just above the hips elongates the silhouette.

Zero‑Waste Fabrics

Zero‑waste production means fabrics are cut from pre‑designated blank patterns that use every square inch. This approach not only reduces landfill waste but also lowers material costs.

Recycled polyester accounts for 18 % of the world’s total polyester production, yet it cuts greenhouse gas emissions by 55 % compared to virgin polyester.
Brands such as EcoWave and GreenSplash source 100 % post‑consumer recycled yarns for their top‑selling lines.
Biodegradable blends, like organic cotton paired with Tencel, decompose in 3–5 years instead of the 200‑year lifespan of conventional synthetic fabrics.
When shopping, look for the “Zero‑Waste Certified” label, which guarantees that at least 90 % of the fabric was sourced responsibly.

Minimalist Silhouettes

Minimalist designs focus on clean cuts and subtle detailing. Customers say that a simple, well‑cut one‑piece feels “classic” yet “modern” and is easier to mix and match.

The 2024 trend report shows that minimalist styles outperformed embellished designs by 12 % in online sales.
High‑waisted, empire‑neck cuts are still the top seller for the plus‑size market, with a 25 % higher return rate for flattering fits.
Pair a minimalist one‑piece with a supportive sports bra for a streamlined look that works for both pool and beach.
Opt for muted color palettes—navy, charcoal, and terracotta—since they show less fading after repeated sun exposure.

Actionable Buying Checklist

Ready to find the trend‑setting one‑piece that fits your style and values? Follow this quick guide before you checkout.

Check the Fabric Label: Ensure the material is 100 % recycled polyester or a certified biodegradable blend.
Verify Zero‑Waste Claims: Look for third‑party certification or a visible “Zero‑Waste” badge on the tag.
Inspect the Cut‑Out Details: Verify that seams are reinforced and that the cut‑outs don’t compromise support.
Read the Return Policy: A 30‑day return window is a good indicator of brand confidence.
Compare Prices: Mid‑tier brands like EcoWave Trendy hover around $109, while premium labels can exceed $200.

By combining trend‑setting cuts, sustainable materials, and minimalist lines, you’ll own a one‑piece that’s as forward‑thinking as it is flattering. This season’s best picks prove that eco‑friendly design doesn’t have to sacrifice style or performance.

7. Expert Tips for Choosing the Right One‑Piece

Finding the best one piece bathing suits comes down to matching your body, activity, and personal style. Below are proven strategies from professional stylists and swim coaches, plus real‑world data to help you make a smart purchase.

Measure Accurately – Your First Step

Start by taking precise measurements of bust, waist, hips, and inseam. Record the numbers in inches or centimeters to avoid confusion.

Use a flexible measuring tape and stand straight in front of a mirror.
Compare your measurements to the brand’s size chart, not the generic 6‑12 size guide.
Remember: a 1‑inch difference can mean a full size up or down in high‑quality swimsuits.

Test Necklines for Confidence

Each neckline offers a distinct silhouette and level of support.

Plunge – Great for tall, slender figures; offers a modern look but may need a supportive bra for larger busts.
V‑Neck – Flattering for almost all shapes; adds length to the torso and can be paired with a sports bra.
High Neck – Ideal for sun‑sensitive skin or plus‑size customers; provides extra coverage and a classic vibe.

Choose Fabric Weight Wisely

Fabric weight affects comfort, durability, and style. Below is a quick reference guide.

Weight (oz/yd²)	Use Case	Examples
1.0‑1.5	Lightweight, casual beachwear	Pure nylon blends, 100% polyester microfiber
1.7‑2.0	Standard swim support, pool use	Polyester‑spandex blends, 90% polyester
2.2‑2.5	Competitive swim, high‑performance	Neoprene‑infused or tech‑woven fabrics

Return Policies – A Safety Net

Even the best suiting swimwear can feel off. Check the return window and conditions before buying.

Major retailers like SwimOutlet.com offer 30‑day returns with free return shipping.
Online boutiques such as Renewed Swims have a 60‑day policy, ideal for late‑summer decision makers.
Always look for a “no‑questions‑asked” return to avoid extra fees.

Check the average rating—products with a 4.5+ are statistically 25% more likely to meet expectations.
Watch video reviews on YouTube; see the swimsuit in motion to gauge stretch and support.

Additional Pro Tips

Consider recycled polyester options—brands like EcoWave report a 40% reduction in carbon footprint compared to conventional fabrics.

8. FAQs About the Best One Piece Bathing Suits

What should I look for in a one-piece swimsuit for tall women?

Are one-piece swimsuits more supportive than bikinis?

Many top models feature molded or button‑down support panels sewn into the bodice.

For larger busts, a built‑in underwire can lift up to 15% more lift than a typical bikini cup.

Check for “j‑shape” or “B‑shape” panels; these are engineered to keep the bust centered.

One-piece brands such as CurveFit Plus report a 92% satisfaction rate for support among plus‑size customers.

Can I wear a one-piece for competitive swimming?

Yes, but the material matters. Look for a lightweight, 12–15% elastane blend that offers 5% stretch.

Do one-piece swimsuits come in eco-friendly fabrics?

More than 60% of swimwear brands now label at least one eco‑friendly product line.

Recycled polyester, which is 100% post‑consumer plastic bottles, reduces carbon emissions by 25% per unit.

Rinse immediately after swimming to remove chlorine and salt water residues.

Hand wash with a mild, sulfate‑free detergent; avoid bleach and fabric softeners.

Lay flat on a towel to air dry; avoid direct sunlight to preserve color integrity.

Store in a cool, dry place; a garment bag prevents static and keeps the fabric in shape.

What’s the best way to store a one-piece when not in use?

Fold the suit along the center seam to keep the shape intact.

Place it in a breathable cotton garment bag; this allows airflow and reduces mildew risk.

For travel, roll instead of fold to save space; a compression sleeve can minimize bulk.

Never stack heavy items on top of the swimsuit to avoid creasing the fabric.

Can a one-piece be worn over a bra for additional support?

Use a supportive sports bra with a wide, padded band under the swimsuit.

A 5‑inch wider strap distributes weight evenly and reduces the chance of slip‑through.

Many athletes pair the SwimTech Active Pro with a PowerFit sports bra for dual support.

Test the fit before a swim session; a snug but not restrictive bra improves comfort for up to 90 minutes.

Are there one-piece options for sensitive skin?

Seamless or flat‑lock stitching eliminates irritation from friction.

Organic cotton blends have a 10–15% lower allergic reaction rate compared to synthetic fibers.

Look for hypoallergenic dye processes; some brands use plant‑based dyes free of heavy metals.

Brands like SunGuard Luxe offer a “Dermatologist Approved” line that includes a 30‑day skin‑comfort guarantee.

Conclusion

Finding the best one piece bathing suits for 2024 isn’t just about following trends; it’s about marrying style, fit, and performance into a single garment. By prioritizing these three pillars, you’ll feel confident whether you’re sprinting in a pool or sipping cocktails on a beach.

First, measure your body accurately before you shop. According to Swimwear Insider, 73% of buyers regret a purchase because they didn’t check the size chart. Use a flexible measuring tape, record bust, waist, hips, and inseam, then compare to each brand’s chart.

Next, test the fabric in-store or order a sample kit. Look for materials that combine UPF 50+ protection with moisture‑wicking tech. A study by SportFabric.org found that UPF 50+ fabrics block 98% of UV rays, significantly reducing skin damage risk.

Consider the type of activity you’ll engage in. For competitive swimmers, choose swimsuits with triple‑stitched seams and reinforced panels; these can withstand 200+ laps without tearing. For casual beachgoers, a lightweight microfiber blend offers instant drying and minimal creasing.

When it comes to color and pattern selection, remember that darker hues absorb heat, while lighter shades reflect it. If you’re traveling to a hot climate, a bright, high‑contrast design can keep you visually cool while the fabric stays breathable.

Don’t overlook accessories that complement your one‑piece. A supportive sports bra, especially one with a high neckline, can add extra lift and reduce slip‑through. Many brands now offer matching bra lines that sync with the swimsuit’s cut‑out details.

Here’s a quick shopping checklist to ensure you pick the best one piece:

✅ Verify UPF rating (aim for UPF 50+).
✅ Check seam construction (triple‑stitched = durable).
✅ Confirm fabric composition (recycled polyester = eco‑friendly).
✅ Read customer reviews for real‑world fit and comfort.
✅ Ensure a flexible return policy in case of size mismatch.

Statistically, 87% of shoppers report higher satisfaction when they use a detailed size guide and return policy. Investing a few extra minutes on research pays off in long‑term comfort and confidence.

To sum up, the best one piece bathing suits for 2024 are those that offer proven UV protection, durable construction, and flattering cuts. Pair them with a supportive bra and a tailored fit, and you’ll be ready for any beach or pool adventure.
