When you have a D-cup or up, finding a great swimsuit is just as much about support as it is about style. It's about feeling confident and comfortable, whether you're lounging by the pool, playing beach volleyball, or taking a dip in the ocean.
The best swimsuits for larger busts are designed to lift, support, and shape while allowing you to move freely without feeling constrained. You want something that will stay put no matter what you're doing, so you can focus on enjoying your time in the sun without constantly adjusting or worrying about support.
Ahead, we've pulled the best swimsuits for women in the large bust category. Whether you're looking for a bikini or a one-piece, need a maternity suit or something that can withstand water sports, we've found the very best suit for every scenario — without ever sacrificing security or comfort. And for more of the best swimsuits that can accommodate larger bust sizes, see our article on the best plus-size swimwear.
How we tested for the best swimsuits for large busts
We tested swimsuits that tout extra bust support. We looked for brands that called out supportive styles designed for bigger boobs, like Andie's maximum bust support suits or Vetchy's DD+ sizing options.
We prioritized brands with bra sizing. The swimwear industry has come a long way from strictly alpha sizing. We love TA3's huge collection of swimwear with cup sizes up to a K and specific bra-sized styles like Boden's Rhodes Cup-Size Swimsuit
We looked for specific features like underwire, molded cups, lining, and thick straps. After testing dozens of swimsuits, we determined that these design details are the most important for providing lift and support while maintaining comfort.
Our top picks had to be size-inclusive. For example, our best overall pick, the TA3 Lifty, goes up to a 4X, J/K Cup.
Editor-favorite picks, tested over two years
With a corseted back that magically snatches your waist, built-in underwire that lifts the breasts, options for short and long torsos, and suits available in your exact cup size up to a J/K, this is one of our top picks for its highly supportive fit.
This under-$50 bikini set has a split-strap that helps distribute weight evenly across your shoulders and a high-waisted bottom that stays in place.
At first glance, it looks like a basic crinkle swimsuit—but there’s hidden underwire and plenty of support packed in.
With thousands of five-star Amazon reviews and a price tag of under $40, this suit is lauded by customers for its comfort, confidence-boosting cut, and great support for DD cup breasts and above.
Pool days are lots of fun in this fully lined swimsuit with molded cups. It supports a larger bust and is cute enough to wear as a top.
Best overall: TA3 The Lifty
TA3 makes the swimsuit of 'Shark Tank' fame that doubles as shapewear. In our review of TA3 swimsuits, we found that the brand deserves a spot among the best swimsuits for large busts thanks to its lightweight activewear compression material, which is not all that dissimilar to a super supportive sports bra.
Executive Editor of Insider Reviews, Sally Kaplan, loves the Lifty, which is TA3's style with underwire for added support. "I love all of my TA3 swimsuits, but the Lifty is my favorite because the underwire is so supportive and prevents the dreaded uniboob that some one-piece bathing suits can cause. The way the sizing works is nothing short of a miracle. You get to choose your bodice length (short or regular/long), your usual swimsuit size (from XS-4X), and your cup size (from A-J/K,) to get the absolute perfect fit, plus there are a bunch of color options. There's even an option for a high-cut version of this suit here if you prefer to show more leg. I've truly never had a one-piece fit me better!
The thick shoulder straps are comfy and adjustable, and the cups cradle me perfectly with no digging. It even looks super cute as a bodysuit, so you could theoretically wear it with jeans or flowy linen pants and no one would be the wiser. But I know you're all here to find out whether it actually does what it promises to do, which is give you a snatched waist. The short answer is: yes! The longer answer is absolutely yes; the lacing in the back actually works like a dream to cinch your waist in. But the good news is that if you're ever feeling bloated or you just want something a little less compressive, you can always just loosen it up. It's like having two sizes in one!
Anyway, if you have a large chest, you won't regret buying this suit — as someone with an F cup, it's definitely the most comfortable and supportive one-piece I've ever tried."
Best budget: Hilor One-Piece Shirred Tummy Control Bathing Suit
Amazon is a treasure trove for affordable, high-quality swimsuits, including some of the best swimsuits for large busts. (Read our full list for the best swimsuits on Amazon.)
This pick has thick, sturdy straps to offer full support for larger cup sizes. People particularly love the built-in bra cups, which can accommodate larger bra sizes.
If you want a modest suit that doesn't look dated or cost too much, this is a fantastic pick. It gets tons of praise for being no-frills and not overly revealing. It's designed to cover your full backside, so you don't have to fear any wardrobe malfunctions. And the midsection is compressive and supportive but not overly tight.
Other details include a ruched midsection designed to highlight curves and a plunging V-neckline. There are over 30 colors and patterns.
Best crinkle suit: Bleu Rod Beattie Square Neck Ribbed One-Piece
The straight size version of this suit (linked above) is available in sizes 4-14. But there's also a plus-size version of the Square Neck Ribbed One-Piece in sizes 16-22.
Classic crinkle suits like the ones we tested from Youswim are admittedly extremely comfortable, but they are not known for offering much in the way of chest support (not for these DDDs, anyway). At first glance, you'd have no idea that this Bleu Rod Beattie suit actually has built-in underwires because the silhouette just looks like a plain crinkle suit — and that's one of the reasons I love it so much! What's hiding underneath is a miracle combo of chest support, lift, and just enough compression to make the suit cling to your every curve without feeling tight or restricted.
I first saw this bathing suit in the mall while panic-shopping for a recent vacation, and between the interior support and the adjustable straps, it might actually be the best-fitting bathing suit I've ever owned. It comes in both regular and plus sizes, and the interior cups have a ton of stretch so they're meant to be flexible enough for multiple cup sizes. In true crinkle suit form, it really does stretch and mold to your shape in a way that's both flattering and extremely comfy. — Sally Kaplan, executive editor, Insider Reviews.
Best budget bikini: Cupshe DD+ Bikini Set
This under-$50 bikini set has a split-strap that helps distribute weight evenly across your shoulders and a high-waisted bottom that stays in place.
It's hard to find a good full-bust swimsuit for under $50, but this large-bust specific pick from Amazon-favorite brand Cupshe manages to be both affordable and supportive.
I'm impressed with how comfortable the bikini top is. It has a cute split-strap design that seems aesthetic, but also adds extra support. This double strap helps distribute weight evenly across your shoulders, so you won't have to deal with narrow halter ties that cut into you.
The downside is that you buy the bikini as a set, so you can't pick separate sizes for the top and bottom. But whereas I usually feel like I have to size up in the top (I usually get a large or even extra large to accommodate a larger bust), I decided to go for a medium since the top is already designed for DD+ cups. The medium top and bottom fit perfectly, so I'm happy I didn't size up. — Samantha Crozier, style editor, Insider Reviews.
Best patterned one-piece: Boden Rhodes Cup-Size Swimsuit
This Boden suit comes in four ridiculously cute patterns, including the paisley-adjacent print above. It's sized according to your bra measurements alone, which I was originally skeptical about, but it ended up fitting perfectly.
The Rhodes Cup-Size Swimsuit has removable straps, so you can also wear it as a strapless one-piece. I tried to wear it sans straps, but there wasn't enough support for me to feel comfortable. Despite the fact that there's a grippy strip that lines the top, it kept drooping, risking a wardrobe malfunction. But with the straps on, I felt secure and supported. It even stayed put when I took a tumble off the floatie pictured above.
I also love how it fits. The torso isn't overly tight, but it is fully lined for structure rather than compression. Plus, the paneling is smartly designed to emphasize your natural waist. — Samantha Crozier, style editor, Insider Reviews.
Best one-shoulder: Summersalt The Sidestroke
While you might not think a one-strap top makes for the best swimsuit for large busts, this Instagram-famous color-blocked suit holds up despite its risky appearing silhouette. "I'm incredibly happy with how supportive the suit ended up being. There was no issue with lopsidedness or sagging, and the diagonal seaming on the front was super flattering," wrote Executive Editor Sally Kaplan in our review of Summersalt swimsuits.
Style writer Sarah Chiwaya also raved about this suit in her guide to the best plus-size swimwear: "Instead of just sticking with one cross strap in the back, this style has two, which distributes bust weight more evenly and doesn't dig. I was happily surprised that this style worked as well as it did on me, as most one-shoulder styles leave me lopsided and uncomfortable," she writes.
To tip the scales even more, this suit is made from recyclable materials and comes in 11 designs. It has 4.5 stars and over six thousand reviews on the Summersalt website, with reviewers raving about how comfortable it is and how flattering the diagonal colorblocking and seaming is. Sizes 2-22 are available.
Best color variety: Vetchy Laguna Bikini
Vetchy's signature swimsuit is the Laguna Bikini, which features an underwire top and a choice between a cheeky bottom and a full-coverage bottom. This two-piece is available in almost every colorway you can imagine, from metallic-flecked numbers to gingham prints.
But the amazing thing for people with large busts is that the top is available in DD+ sizes. An SDD+ will fit bra sizes 32DD-32E, while an LDD+ fits sizes 36DDD-34G. This does exclude people with band sizes larger than 36, however.
"As a 34DD, I tried the MDD+ size, which fit great. I love the underwire support and the option to remove the padding in the cups. But I especially love how wide the straps are. They fit comfortably on my shoulders and support the weight of my chest. The straps are also adjustable, which is a super important feature for a bra-like bikini." — Samantha Crozier, style editor, Insider Reviews.
This bikini is a great classic silhouette and also one of the best underwire swimsuits we've tested.
Best active: Andie the Maui Top and Bikini Bottom
"At one point, I forgot I even had this set on under my clothes and I received many compliments on the gorgeous Cherry color.
Unlike most string tops, the weight of your chest is held up by the Maui top at your shoulders instead of your neck, so it feels like a cozy bra. It looked more like a sports bra and thus pushed my chest together in a similar fashion, which felt secure but didn't look particularly sexy. It gave some 'uniboob' vibes, but it wasn't awful — just not like bikini tops I'm used to.
I'd wear this supportive, comfortable swimsuit for activities like visiting a water park, surfing, or attending a family function because it feels secure and sensible. But it's not the most exciting-looking set for lounging on the beach with friends or going on vacation with my boyfriend." —Paige DiFiore, lifestyle & entertainment freelance editor

Best tankini: Swimsuits for All Bra Sized Underwire Tankini Set
In addition to the top of this set being available in a wide range of bust sizes, you can also pick the bottom size between 8 and 26. This is a welcomed option for those of us who have trouble with sold-as-a-set-in-a-single-size bikinis.
The tankini, which comes in a classic black with just a bit of mesh detailing for added flair, has adjustable straps and a hook closure with three adjustments in the back. The fit-and-flare silhouette is universally flattering, while the shorts bottoms allow for extra coverage.
Best underwire: CUUP The Scoop Swim Cup and Highwaist Swim Bottom
We're fans of CUUP's bras and the brand recently came out with a line of some of the best swimsuits for large busts. They make excellent underwire bikini tops that are available in your exact bra size and this balconette swim top finds additional support in the form of thick recycled nylon straps that are adjustable.
Despite its cheeky silhouette, the high-rise bottom stays put. Plus, the swimsuit's material is chlorine, salt water, sunscreen, and fade-resistant with UPF 50 protection.
Best convertible: Curvy Kate Wrapsody Bandeau Strapless Multiway Swimsuit
Best for minimizing bust: Lands' End Chlorine Resistant High Neck UPF 50 Modest Tankini Swimsuit Top
The best part of this modest swimsuit is its extensive sizing options. The tankini top is available in regular, petite, and long lengths, as well as plus sizes. There are 11 colorful patterns to choose from, and you can further customize the lycra spandex suit by adding a monogram for an additional charge.
Best plus size: Daci Women Plus Size Two Piece Bikini
This two-piece suit is the perfect combination of security and style. On the top, thick crisscross adjustable straps provide ample support, as does a padded pushup bra. The high-waisted bottom has a full-coverage backside and flattering ruched details. To add some extra excitement to the silhouette, the top features a plunging cutout front, which is secured with crisscross details. The nylon and spandex suit comes in 32 colors and patterns in sizes M-26 plus.
Best on Amazon: Tempt Me One Piece Plunge Mesh Swimsuit
Of Amazon's vast swimsuit offerings, Tempt Me's collection stands out for its inclusive size ranges and extensive color and pattern selections. This top-selling one-piece style has a high neckline accented by a sheer, plunging mesh panel to show just a hint of skin. A padded pushup bra provides solid support. The neck is secured via a hook closure and the back features two more mesh panels. A faux tie waist accentuates curves.
The polyester and spandex material is smooth and comfortable, so it's great for all-day wear. There are a whopping 44 colors and patterns to choose from.
Best maternity: Summersalt The Maternity Cinched Current
In our review of Summersalt's swim collection, we loved nearly everything we tried from the brand. If you're expecting, this maternity suit will be the perfect addition to your summer wardrobe. The square neckline and empire waist seam provide extra support and comfort for a growing belly. Plus, cinched ties at the back of the bust and the sides of the legs help you to tailor this suit for your most comfortable fit, which can be adjusted to accommodate your body's changes over time. Like all of Summersalt's swim offerings, this suit is made from premium recycled fabrics with a UPF 50+ to protect skin during long hours under the sun.
