14 best swimsuits for large busts in 2024 that are actually cute

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 amidst the best swimsuits for large busts thanks to its lightweight activewear compression material, 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. 

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 in 2023.) This elastic and polyamide pick has thick, sturdy straps to offer full support for larger cup sizes. Customers particularly love the built-in bra cups, which can accommodate larger bra sizes. 

Other becoming details include a ruched midsection designed to highlight curves and a plunging v-neckline. There are over 30 colors and patterns.

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 scoop-neck 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.

Andie is one of our favorite swimwear brands for its well-rounded collection racking up over 100 styles with multiple texture and coverage options. Each style is designed to last longer than just a season, using simple but timeless silhouettes. If you're headed to a waterpark or going to play beach sports, we highly recommend this secure set, which will stay put throughout the day's activities. 

Paige DiFiore, our lifestyle & entertainment freelance editor, enjoyed the Maui top with removable cups and adjustable straps because "unlike most string tops, the weight of your chest is held up at your shoulders instead of your neck, so it feels like a cozy bra." In fact, Paige found it so comfortable that "at one point, I forgot I even had this set on under my clothes."

When selecting the best swimsuit for large busts, look for underwire as a support option. This dreamy pink suit from Frankies Bikinis, in a stretchy textured floral fabric from the brand's collaboration with Pamela Anderson, features a dainty bikini top silhouette that is effortlessly stylish and comfortable. It has adjustable straps and a back clasp. When paired with the teeny, stringy Venice bottom, the set makes for eye-catching beach attire.

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.

While most swimsuit companies use what are called "fit models" (having what's considered the "perfect" proportions for a given size) to tailor the way suits lay on the body, Helen Jon actually measures the fit of its suits on "regular people:" its own employees. The Insider reviews team tested a lineup of the brand's swimwear and found it to be stylish, fairly priced, universally flattering, and exceptionally comfortable. 

Our Executive Editor, Sally Kaplan particularly loved this one-piece with a keyhole cutout because it has "a good amount of support thanks to the seam under the bust." Still, it doesn't sacrifice comfort. "Wearing it on the beach, I felt covered and secure, but not at all suffocated or overly conservative. When I got home, I actually lounged around in it for a few more hours because it was just that comfortable," Sally wrote.

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. 

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.

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 have the option to further customize the lycra spandex suit by adding a monogram for an additional charge.  

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.

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 criss cross details. The nylon and spandex suit comes in 32 colors and patterns in sizes M-26 plus.

When looking for the best swimsuits for large busts, fun details such as cutouts can add interesting elements to an otherwise standard black suit. Andie's Crete top has a sweet keyhole opening with a tie in the front. The straps are adjustable, and the top (with removable padded cups) has a hook closure in the back. 

One great thing about Andie's swim collection is that bikini tops and bottoms are sold separately, so you can mix and match sizes and styles depending on your preferences. While a number of their bottoms would pair perfectly with this cutout top, we particularly like it with the low-rise Hipster bottoms.

A longline bikini top provides a bit of extra coverage and support, without going full-on tankini. Athleta's version, made from recycled nylon and lycra spandex, features a deep v plunge neckline and thick straps, which cross and tie in the back. The material has UPF 50+ protection and is quick drying for added comfort when going in and out of the water. The swimsuit is comfortable and stays put, and it's supportive enough to wear while playing water or beach sports.

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.
