Finding a great swimsuit should not feel like solving a geometry problem while standing under fluorescent dressing-room lights. Yet plus size shoppers are often expected to choose among inconsistent sizing, decorative straps that provide approximately zero support, and bottoms that behave beautifullyuntil water becomes involved.
Fortunately, the best plus size swimwear of 2024 offered far more thoughtful choices. Brands expanded their size ranges, introduced adjustable construction, improved bust support, and created one-pieces, bikinis, tankinis, and swim dresses that were designed for curves instead of merely enlarged from smaller patterns.
This retrospective guide synthesizes hands-on editorial testing, professional fit advice, published product specifications, and verified wearer feedback from major American fashion, lifestyle, and retail publications. The leading suits were assessed for fit, comfort, support, coverage, fabric quality, adjustability, water performance, value, and size inclusivity.

How the Leading Plus Size Swimwear Was Evaluated
A swimsuit can look magnificent in a product photograph and become a rebellious piece of fabric the moment its wearer bends, swims, or chases a runaway beach umbrella. Meaningful swimsuit testing therefore goes beyond appearance.
The strongest 2024 reviews considered whether straps dug into shoulders, cups remained secure, leg openings stayed in position, and fabric became transparent when wet. Reviewers also examined stitching, lining, stretch recovery, drying time, coverage, and comfort during activities such as swimming, snorkeling, paddleboarding, and walking along the beach.
Size inclusivity mattered, but a long size chart alone did not guarantee a recommendation. Better brands paired extended sizing with curve-specific pattern grading, supportive bands, adjustable straps, multiple torso options, or cup-sensitive construction. In short, a 4X should be designed as a 4Xnot treated as an XS that spent too much time near a photocopier.
The Best Plus Size Swimwear of 2024
Best Overall: Summersalt The Sidestroke
Summersalt’s Sidestroke remained a standout because it combined a recognizable one-shoulder silhouette with substantial, compressive fabric. The diagonal seaming created visual definition without relying on uncomfortable boning or aggressive control panels. During published wear evaluations, the material was frequently praised for feeling supportive while still allowing normal movement.
The suit was offered in sizes 0 through 24, with selected colors available in a long-torso cut. Its asymmetrical design looked polished enough to wear as a bodysuit beneath wide-leg pants or shorts, making it particularly useful for travel.
Best for: Pool lounging, resort trips, and shoppers seeking smoothing support without underwire.
Consider before buying: One-shoulder construction can feel less secure during vigorous lap swimming, and the size range stopped earlier than those of several dedicated plus size brands.
Best Size Range: Swimsuits For All Sarong Front One-Piece
Swimsuits For All earned attention in 2024 for carrying one of the broadest mainstream swimwear selections, with the overall collection extending from approximately size 4 to 40. Its popular sarong-front designs combined ruching, a draped front panel, adjustable elements, and fuller rear coverage.
The wrapped appearance offered a classic alternative to plain black control suits. More importantly, the brand provided multiple silhouettes, including bikinis, tankinis, swim dresses, board shorts, and bra-sized tops. That variety helped shoppers choose coverage according to their activity and taste rather than according to somebody else’s rules about what a larger body “should” wear.
Best for: Shoppers who value extensive sizing and fuller-coverage options.
Consider before buying: Fit could vary among collections, making the product-specific size chart and return policy essential reading.
Best for Active Swimming: Lands’ End Tugless Tank
The Lands’ End Tugless Tank did not attempt to win a contest for the most complicated collection of cutouts. Its strength was dependable function. The suit’s straightforward tank shape, secure leg openings, substantial lining, and chlorine-resistant options made it a practical choice for water aerobics, lap swimming, kayaking, and family beach days.
Regular, long-torso, and plus size configurations helped address a common one-piece problem: a suit may fit around the body but still be too short from shoulder to crotch. The Tugless design stayed relatively stable during movement, reducing the need for constant readjustment.
Best for: Frequent swimmers and anyone who prioritizes security over runway drama.
Consider before buying: The conservative neckline and rear coverage may feel too traditional for shoppers wanting a fashion-forward suit.
Best Thoughtful Design: Nomads Swimwear
Founded by plus size model and designer Taylor Long, Nomads built its identity around inclusive patternmaking instead of treating extended sizes as an afterthought. During the 2024 season, the brand offered sizes from XS through 5X and used bold colors, sculptural necklines, high-rise bottoms, and adjustable details.
Nomads’ designs were especially appealing to shoppers who wanted sophisticated plus size swimwear that did not automatically translate “supportive” into “matronly.” The brand’s online fitting tools and detailed guidance also reduced some of the uncertainty of ordering swimwear without trying it on first.
Best for: Distinctive silhouettes and genuinely curve-conscious construction.
Consider before buying: The premium price and relatively short return window required more careful pre-purchase measuring.
Best for Bust Support: Torrid Underwire Swimwear
Torrid’s swim collection was developed specifically for plus size figures and generally covered sizes 10 through 30. Its underwire tops and one-pieces stood out for bra-inspired features such as adjustable straps, molded cups, supportive bands, and hook-and-eye closures.
These elements provided more reliable lift and separation than a basic shelf bra, particularly for full-bust shoppers. Torrid also sold coordinating high-rise bottoms, swim shorts, rash guards, and cover-ups, allowing different top and bottom sizes to live together peacefullyas nature intended.
Best for: Larger busts and shoppers familiar with bra-style sizing.
Consider before buying: Underwire placement must match the wearer’s breast root correctly; the wrong size can pinch rather than support.
Best Affordable Separates: Old Navy Mix-and-Match Swimwear
Old Navy brought cheerful colors, prints, and practical silhouettes to a comparatively accessible price category. Its extended online sizing and mix-and-match format allowed shoppers to pair different sizes, coverage levels, and styles.
High-rise bottoms, scoop-neck bikini tops, tankinis, and long-line designs made the collection particularly useful for building an inexpensive swim wardrobe. Adjustable straps appeared on many styles, although construction and support varied from piece to piece.
Best for: Budget shopping, family vacations, and experimenting with color.
Consider before buying: Popular extended sizes often sold out early, and lightly structured tops were not ideal for every large bust.
Best High-Waisted Bikini: Tempt Me High-Waisted Bikini
Tempt Me became a popular Amazon choice by offering a broad selection of affordable two-piece suits, including styles extending to size 26 Plus. The brand’s sporty high-waisted bikini combined a scoop-neck top, wide straps, and a high-rise bottom that offered more coverage than a traditional bikini brief.
Thousands of consumer reviews praised the balance of comfort, price, and support, including positive feedback from wearers with DD and larger cup sizes. The top’s broad band distributed pressure more comfortably than tiny halter strings, which tend to turn shoulders into unwilling load-bearing structures.
Best for: An inexpensive, secure two-piece for casual swimming.
Consider before buying: Sizing and fabric thickness varied among colors and designs, so reviews for the exact variation mattered.
Best Sculpting Swimsuit: TA3 Plungey
The TA3 Plungey paired a dramatic neckline with corset-inspired adjustability. Its lace-up back let the wearer customize waist compression, while adjustable straps, removable cups, and firm fabric provided structure. Different torso lengths were another meaningful advantage for people who usually find one-pieces too short or baggy.
The sculpting effect was unmistakable, but the suit still looked like fashionable swimwear rather than shapewear that had accidentally wandered onto a beach. It could also be styled as a bodysuit after the swimming portion of the day ended.
Best for: Customizable waist definition and a dramatic resort look.
Consider before buying: It was among the most expensive options, and its deep neckline revealed substantial cleavage.
Best Adaptable Fit: Good American Always Fits Swim
Good American’s Always Fits fabric was designed to stretch across a range of neighboring sizes, making it useful when body measurements fluctuate. The 2024 swim collection included sleek one-pieces and bikinis with minimalist styling, bright colors, and sculpting stretch.
The flexible fabric reducedbut did not eliminatethe importance of fit. A bust still needs sufficient coverage, and leg openings still need to lie flat. Nevertheless, the concept offered welcome flexibility for travelers, people between sizes, and anyone tired of treating a swimsuit label like a binding legal contract.
Best for: Weight fluctuations and sleek contemporary styling.
Consider before buying: Some minimal designs offered less adjustability and bust structure than conventional bra-sized swimwear.
Best Vintage-Inspired Styles: ModCloth Swimwear
ModCloth’s plus size swim selection leaned into retro details: sweetheart necklines, halter tops, polka dots, swim dresses, high-waisted bottoms, and playful prints. These shapes delivered coverage without making coverage the entire personality of the garment.
The assortment changed regularly and included products from multiple labels, so fit was less uniform than it was at single-brand retailers. Still, ModCloth was one of the strongest destinations for shoppers who preferred old-Hollywood charm over another generic black tank suit.
Best for: Retro fashion, colorful prints, and swim dresses.
Consider before buying: Consult the chart for each individual brand rather than relying on a previous ModCloth purchase.
How to Choose Plus Size Swimwear That Actually Fits
Measure Your Body Before Ordering
Take bust, underbust, waist, hip, and torso measurements while wearing minimal clothing. For torso length, run the tape from one shoulder down through the legs and back to the starting shoulder. Compare those numbers with the chart for the exact swimsuit, not a retailer’s general chart.
Match the Support to the Activity
Sunbathing does not demand the same construction as paddleboarding. For active days, prioritize wide straps, secure closures, stable leg openings, substantial lining, and a neckline that remains in place when leaning forward. Underwire, bra-sized cups, and firm underbust bands can improve full-bust support, but only when positioned correctly.
Look Beyond the Phrase “Tummy Control”
Compression is a preference, not a requirement for admission to the beach. If smoothing feels good, look for double-layer fabric, power mesh, ruching, or an adjustable corset panel. The suit should feel firm but should not restrict breathing, roll at the openings, or make lunch seem like a dangerous hobby.
Check the Suit When It Is Wet
Swim fabric often relaxes in water. A proper suit should remain secure without cutting into the skin when dry. Before removing tags, confirm that light-colored material is fully lined and perform a movement check: sit, squat, raise both arms, and lean forward.
Real-World Swimwear Experience: What Testing Reveals After the Mirror Check
The first five minutes in a swimsuit can be misleading. Fresh from the package, supportive fabric feels crisp, the straps are carefully adjusted, and everything appears ready for its glamorous resort debut. The more revealing test begins after an hour of actual movement.
During a typical beach-day trial, a dependable suit disappears from attention. Wide straps spread pressure instead of carving narrow lines into the shoulders. A high-rise bottom stays at the waist after sitting on a towel and standing again. The bust band remains level across the back, while the cups continue to contain breast tissue when the wearer bends to pick up a bag. That absence of constant adjustment is one of the clearest signs of a successful fit.
One-pieces introduce a different challenge: torso length. A suit that is too short may pull down at the neckline and upward at the leg openings simultaneously, an engineering achievement nobody requested. Long-torso options from brands such as Summersalt and Lands’ End made a noticeable difference for taller wearers and people whose height is concentrated through the body. Adjustable straps helped, but they could not completely repair a fundamentally short torso.
Water also exposed differences in fabric quality. Firmly woven materials from performance-oriented suits generally retained their shape after swimming, while thinner budget fabrics sometimes became looser and required readjustment. That did not automatically make inexpensive swimwear a poor purchase. A budget bikini could be excellent for an occasional vacation, especially when its top had wide straps and its bottom was fully lined. Frequent pool users, however, benefited from paying more for chlorine-resistant material and reinforced seams.
Support preferences varied considerably. Some full-bust wearers felt most secure in Torrid’s underwire construction, particularly when cups and bands could be selected with bra-like precision. Others preferred the flexible compression of the Summersalt Sidestroke because there was no wire to press against the ribs while lounging. Neither approach was universally superior; the better choice depended on breast shape, activity, and sensitivity to structured cups.
Two-piece suits often produced the easiest overall fit because tops and bottoms could be purchased separately. A shopper might need a larger top, a smaller bottom, and absolutely no opinion from the fashion industry about whether those numbers were supposed to match. High-waisted briefs also made restroom breaks simpler than they were in one-piecesa practical victory rarely celebrated in glossy swim campaigns.
The final lesson was psychological as much as technical. The best plus size bathing suit was not necessarily the one that made a body appear smallest. It was the suit that remained comfortable enough for its wearer to swim, socialize, play with children, or nap beneath an umbrella without conducting a fabric inspection every six minutes. Secure construction creates confidence, but confidence does not require hiding. Bright bikinis, plunging one-pieces, swim dresses, rash guards, and classic tanks all earned their place in the water.
Final Verdict
Summersalt’s Sidestroke was the strongest all-around plus size swimsuit of 2024 for its supportive compression, polished styling, and long-torso option. Swimsuits For All delivered the broadest variety of sizes and silhouettes, while the Lands’ End Tugless Tank was the practical winner for frequent swimming. Nomads offered some of the most thoughtful curve-specific design, and Torrid remained a reliable destination for structured bust support.
No single swimsuit can serve every body, cup size, activity, and coverage preference. Start with accurate measurements, decide how much structure you want, and choose a return policy that permits a careful indoor fit check. A great swimsuit should support the day you plan to havenot assign you a smaller life beside the water.
