25 Best One-Piece Swimsuits, According to Reviewers & Glamour Editors

The brand is called Miraclesuit for a reason: It makes figure-hugging swimsuits that support and look good. Its bathing suits with tummy control are ideal because of the slimming design—this ruched one-piece drapes diagonally across the stomach for extra control. “I’ve tried so many swimsuits, and this is the only suit that really fits,” an Amazon reviewer writes. “I’m large-busted with small hips, and this suit fits perfectly. It gives awesome support and doesn’t sag when wet.”

Sizes: 8–18 | Fabrics: Nylon, spandex | Colors: 13 | Padding: Yes

“I’ve worn this V-neck in classic black for more than five years and get compliments on it all the time,” Glamour commerce editor Malia Griggs says. “Its plunging cut draws attention to my smaller chest, which I like, and its ruching is loose and comfy against my midsection. I especially appreciate that its fabric has UPF 50 sun protection woven in! I actually wear the suit year-round as a bodysuit under skirts and pants.” The one-piece comes in a wide range of colors, includes long-torso sizing, has removable cups, and is (blessedly) machine-washable.

How gorgeous is this best-selling one-piece from Free People? Its deep scoop neck shows off some cleavage, while its super-high cut and extra-cheeky bottom pull focus to your legs and butt. The suit is easy to pull on, a little compressive, and comes in a multitude of splashy colors (like this beetroot pink, a sky blue, and yuzu yellow).

Two swimsuits in one? We’ll take it. Head over to Amazon’s swim section for this gorgeous one-piece that just happens to be reversible. Add a pop of color with a vibrant floral print on one side and keep it minimal with a simple baby-blue-and-white palette on the other. “I’m a sucker for all things bows—currently one of 2024’s biggest fashion trends—so when I saw this reversible suit on Amazon, I couldn’t resist, though I had my doubts that something only 20 bucks could be high enough quality to keep me looking snatched,” says Glamour’s Schwartz. “It really surprised me. Not only is the crazy-soft fabric thick enough to provide tummy control, but it also offers boob support, and the straps were easy to tie. Plus, it’s two suits in one. This was a big win.”

Sizes: XS–XL | Material: Nylon, spandex | Colors: 11 (22 when reversed) | Padding: No

Forget trends and high cuts—sometimes all you want is a classic suit that’ll last summer after summer. The Andie is our pick, especially if you're looking for coverage from top to bottom. “For days where I just want a little extra coverage, I always reach for my Andie Amalfi suit,” says Glamour reviewer Ana Lawrence. “While I love just laying out at the beach, I do consider myself a big swimmer, and this suit keeps everything secure no mater how choppy the waters are.”

Sizes: XS–XXL | Material: Recycled nylon, spandex | Colors: 10 | Padding: Yes (removable)

Summersalt is known for its breezy, versatile styles, fun colors and patterns, and generous sizing (including long-torso fits). “The Perfect Wrap has thin sewn-in boob pads that don’t shift or come out in the wash, which is a big pro!” says Glamour tester Katherine Howell-Kiser. “Also, you can adjust the wrap and make it tighter to achieve a more snatched looked if you want.” Its butt coverage is a little cheeky, and we appreciate that the suit is mostly made of a recycled material.

Sizes: 2–22 | Material: Recycled polyamide, spandex | Colors: 13 | Padding: Yes (sewn-in)

Not into cups or underwire in your swimwear? Not a problem. This comfortable wrap bathing suit has removable cups for a smooth, seamless finish—and the color-block design is a nice change-up from basic black. “After using this bathing suit all summer, I want to say that it held up so well,” one of the many Amazon reviewers says. “It’s so comfortable, easy to clean, and the ties are adorable. I plan on using this over and over again because the quality is amazing. The coverage is nice and keeps you feeling secure. I also got a ton of compliments on this bathing suit.”

Sizes: XXS–XXL | Material: Chinlon, spandex | Colors: 7 | Padding: Yes (removable)

Glamour assistant market editor Kathleen Thomas was initially hesitant about buying a one-size-fits-all suit, but the Domino put her worries to bed. “It’s made of magical particles that somehow fit to the form so nicely and flatteringly,” she says. “My friends have also tried the suit and it looks amazing on all of them.” Its stretchy ribbed fabric is lightly compressive but comfy, and two rings along the thick straps add a retro vibe.

Sizes: One size only (fits 2–12) | Material: Nylon, Lycra spandex | Colors: 5 | Padding: No

This ribbed one-piece almost qualifies as a high-waist bikini, with two components that ultimately connect below the bust. We love how it shows some skin (a bare shoulder! a flash of abs and backA) without feeling too revealing, and that it comes in so many bold colors. The leg cut is high, and the back coverage is moderate.

Sizes: XS–XL | Material: Micronylon, spandex | Colors: 9 | Padding: No

Between the keyhole cutout, gold hardware that cinches you along the bust, and supportive double lining, it’s little wonder that this Gooseberry suit is a go-to for celebs. “I was intrigued by this one-piece initially because I knew Blake Lively was a fan—and who doesn’t want to be like Blake?” says Glamour senior editor Stephanie McNeal. “It soon became one of main suits in this summer’s rotation. I love how it’s chic and trendy while still not being so revealing that I can't wear it to my pool with my toddler—and I think the cutout in the front adds a little pizzazz. It also feels well-made, which is rare sometimes for a bathing suit.”

Sizes: XS–XL | Material: Polamide, elastane | Colors: 6 | Padding: No

Amazon shoppers can’t get enough of this Cupshe one-piece. Yes, the scalloped design with its triangular cutout is supercute, but the majority of its more than 5,000 ratings mention how flattering its silhouette is. The fabric is very stretchy, and you don’t have to worry about any uncomfortable underwire up top. “I feel great that it won’t slip off or let things pop out in any way like other two-pieces do. And it is not bland like some one-piece swimwear is,” one Amazon reviewer writes. “The cups don’t push up and in, but that feels nice as they sit securely. I’m relieved that the suit covers my bum (most ride way up). I’ve had many compliments on the vintage look and quality and how the unique cut of the suit complements my body shape. It is easy to get on and off, and it seems like it will last.”

Sizes: XS–XXL | Material: Polyester, spandex | Colors: 4 | Padding: Yes (removable)

The thing about Amazon is that you really can find anything, including swimsuits for every type of summer activity. This basic black one-piece with a classic scoop neck and supportive underwire for bigger boobs is elegant enough to wear all summer long. Bonus: Its lace-up back lets you control how fitted it is.

Sizes: 0–16 | Material: Nylon, spandex | Colors: 3 | Padding: Yes (removable)

Ribbing adds texture and compression to an otherwise basic swimsuit, making it a popular choice. “When I want to wear something different from my black one-pieces, I like this Madewell suit,” says Glamour's Griggs. “It’s high-cut along the legs without being too high-cut, and I love how poppy and fresh its orange colors are. I’m eyeing the cool pink too.”

Sizes: XXS–4X | Material: Recycled polyamide, spandex | Colors: 3 | Padding: Yes (removable)

Glamour associate beauty editor Danielle Sinay calls this the only swimsuit she bothers wearing. “I have very large breasts (am currently a size 36F or G, for context) and never felt secure in any swimsuit I tried on unless I looked like I was going scuba diving with a team of grandmother nuns—meaning that only the most matronly and least cute options are what provided actual support. That is until I found TA3’s square-neck suit!” she says. “It essentially functions as gorgeous shapewear with a built-in bra. Ever since getting mine (which I now have in several colors), I actually feel comfortable going to—and running on—the beach!”

Sizes: XS–4X (up to K-cup bust sizing) | Material: Nylon, spandex | Colors: 5 | Padding: Yes (removable)

One thing you don’t see often in swimwear is bra sizing. This Boden one-piece fits according to your cup and measurements so you can get the most support—and coverage—for the girls. The Kate Middleton–beloved brand is a top pick for Glamour editors, too, and who could blame us? Pair this pretty suit with a red lip for the total 1950s pinup look. “This is my all-time favorite bathing suit,” says Glamour’s Schwartz. “It took decades to find a one-piece that could give me the same support, lift, and shape as a bikini top or a bra, so when I found Boden, I haven’t looked back. It comes in a variety of different prints, from tropical to preppy, and they wash so well without fading. Plus, they’re actually comfortable—no painful boning—and keep me sucked in. I’ve turned all of my friends on to them, too, and now they’re converts as well.”

Sizes: 32A–38DD | Material: Polyamide, spandex | Colors: 4 | Padding: Yes

Here’s the hot-girl summer one-piece swimsuit of your dreams: This L Space knockout mimics a yin and yang with its black-and-white color-blocking that’s split with a curve of cutouts along the bust, stomach, and back. “This is probably the most daring swimsuit I’ve ever owned,” says Glamour tester Emma Stein. “But hey, I’m proud of my body, and I love how its cutouts hug my curves to show some skin—without actually showing off more than feels comfortable.”

Sizes: XS–XL | Material: Nylon, spandex | Colors: 3 | Padding: Yes (removable)

Want to cover your bust and arms in a more subtle way? Snag this unique off-shoulder piece immediately. It still has straps for support but with a ruffled layer that keeps your chest hidden completely. Plus, we love the laser-cut lace detailing. “I bought this for a trip to Mexico and it was great. It was very comfy for all-day excursions, and I liked that I could put shorts or a skirt over it and it just looked like a regular top,” an Amazon reviewer writes. “It was also very flattering on my curvy figure. The suits are true to size and look great even after being washed.”

Sizes: XS–22 Plus | Material: Nylon, spandex | Colors: 10 | Padding: Yes (removable)

“I feel so sexy in this swimsuit—something I don't say often, if ever, about swimsuits,” says Glamour’s Griggs. “Its plunging neckline draws attention to my (smaller) boobs, but the material is lightly compressive and smoothing enough to keep them in place (as well as my tummy). I really like the crisscross and deep cut of the back as well, which pulls some attention to my butt without going overboard. Lastly, the color! I’m in love with this bright purple—it makes me look tan. The suit is so comfortable and cool that I wear it as a bodysuit—like I do in this picture.” The shoulder straps are not adjustable, but Griggs says this has never been an issue, as they stretch and hold shape.

Sizes: XS–XXL | Material: Nylon, polyester, Lycra spandex | Colors: 14 | Padding: No

The internet can’t get enough of Good American’s viral swimsuits. Each one is designed with a special fabric that stretches up and down in size to hug your body as it goes through natural fluctuations (making it one of the best maternity swimsuits and postpartum swimsuits). Its straps are adjustable, so the fit always works, and the high cut design is on-trend this summer. “The quality is phenomenal, it’s comfortable, and fits perfectly,” says a Good American reviewer. “I love that the material hides my insecurities. I wanted a one-piece that wasn’t a ‘mom’ one-piece and still felt appropriately sexy. It’s perfect!”

Sizes: XXS/XS–4XL/5XL | Material: Polyester, spandex | Colors: 2 | Padding: No

Long-sleeve swimsuits are a smart call for anyone who wants more sun protection (like surfers, say) or coverage. Glamour’s Schwartz particularly likes this Stylest suit’s versatility, which looks more like clothing than something you can swim in (and she's actually worn it as a top while on vacation). It has cute puff sleeves, built-in shapewear and a shelf bra, and UPF 50+ in the fabric.

Sizes: XS–2X | Material: Polyamide, elastane | Colors: 9 | Padding: No

Glamour tester Howell-Kiser calls the Sidestroke “very figure-flattering” and praises its double-layered fabric, which offers great stomach support. The modest one-shoulder suit shows a little skin while maintaining full coverage along the butt. Its wide range of sizing and tummy control make it an excellent postpartum swimsuit.

Sizes: 0–24 | Material: Recycled polyamide, elastane | Colors: 15 | Padding: No

Out of her many swimsuits, this high-neck one-piece is a standout for professional surfer Anastasia Ashley. It’s largely made of comfy, stretchy recycled spandex and polyester, and its splashy floral pattern nods to the family-run business’s Hawaiian roots. “I love high-neck one-pieces,” Ashley says. “They feel sophisticated and fancy enough to wear with pants or shorts after the beach. This brand has the best patterns and colors, and I especially like this blue suit. Anything that’s tropical or ‘coconut girl’ fits my style.”

Sizes: XS–XS | Material: Recycled spandex and polyester | Colors: 1 | Padding: Yes (removable)

Miraclesuit’s stylish take on a swim dress cinches in your waist and stomach and looks damn good doing so. The side slit in its skirt shows off your leg while cleverly hiding your bikini line, and its underwire and plunging neckline push up your boobs while ensuring they don’t bounce around. “I was hesitant at the price, but after six months, I still love this swimsuit so much! So glad I took the splurge. It’s very flattering, smoothing, and the skirt is perfect without feeling too matronly,” an Amazon reviewer says.

Sizes: 8–16 | Material: Nylon, Lycra spandex | Colors: 6 | Padding: Yes
