Few things ruin a relaxing day at the beach or pool more than the constant worry that your swimsuit isn’t doing its job (i.e. keeping you covered without having to constantly readjust) — and, if you have a bigger bust, you’re probably familiar with that feeling. Luckily, there are plenty of big-boob-approved, size-inclusive swimsuits out there. Whether one-pieces, bikinis, or tankinis, the best swimsuits for big busts are actually supportive — and I’ve rounded up 15 of the cutest ones of the season.
When shopping for the best swimsuits for big busts, first keep an eye out for swimsuits that offer adjustability and customization — think adjustable and removable straps that you can wear in whatever way feels most comfortable for you. Next, look for supportive features like molded cups, removable padding, or built-in shelf bras that help add lift, shape, and support. Many swimsuits also incorporate underwire or supportive bands around the rib cage, just like a bra, which can help evenly distribute the weight of your breasts (and offer definition). Lastly, opt for swimsuits with tops that prevent spillover, such as full-coverage cups or a longline style.
Whether you’re in the market for a full-coverage one-piece or a sultry bikini, scroll on to shop the best swimsuits for big busts — all conveniently available on Amazon.
The cutout trend is still going strong, and you can enjoy that trend at the beach with this one-piece swimsuit, complete with a cutout at the sternum. Good news for folks with bigger busts: It feels as supportive as your favorite bra, thanks to adjustable racerback straps and removable, padded push-up cups that offer just the right amount of lift. The bottoms are fuller coverage for a hint of modesty.

A triangle bikini that actually provides coverage and support? Yes, please! This V-neck halter top has two ties — one around the neck and one around the ribcage — so it’s completely adjustable. Removable cups add shape, while a supportive waistband adds lift and helps the top stay in place. Plus there’s adequate coverage on the sides to help prevent spillover, along with a high-rise, full-coverage bottom with ruched details.
Helpful review: “I'm a 42DD and this fits perfectly. Very comfortable, love that there is no underwire yet the halter provides lots of lifting support.”

“Hot” and “supportive” can coexist, and this high-waisted bikini proves it. The V-neck top has removable push-up padding, while a thick and supportive band around the ribcage creates a smooth silhouette and prevents spillover. The adjustable straps can be converted into a racerback style, if that feels more comfortable. Full-coverage, high-waisted bottoms with ruching at the front complete the look.
Helpful review: “Great suit if you are large-busted. I'm a 36F and felt comfortable and supported. Nothing digging in, nothing over-spilling! I'll probably get this in more colors!”

And it has a cute ruffle trim, to boot. The high-waisted, full-coverage bottoms come in 17 floral or botanical prints that perfectly complement the solid-colored top.

This vintage-inspired halter swimsuit has not one, not two, but three support straps: There are two tie closures (one at the back of the neck and one around the ribcage), as well as an extra ribcage strap with a clasp closure. The push-up padding, wide side panels, and twist accent help push your breasts forward and up for hold and definition. High-waisted, full-coverage bottoms with a ruching effect add to the retro-chic vibe.
Helpful review: “The color is vibrant and the quality of the suit is great but my favorite part is that my boobs don't spill out of it when I'm walking/splashing around in the water or chasing after my kids! I love it so much I just purchased a second one in a different color and pattern. Highly recommend!”

This bustier-style bikini top feels more like your favorite bra than a bikini top, courtesy of its underwire and cups that encapsulate each breast for maximum support. The adjustable straps are extra-wide, so they won’t dig into your shoulders, while the longline style and two back straps with clasp closures keep you secure. The bright polka-dot print pictured is so adorable, but it comes in eight more prints and colors as well, including neon yellow, cherry print, and purple snake print. Find a range of coordinating bikini bottoms here.

This flowy tankini will let you focus on enjoying your margarita (or other poolside beverage of choice), rather than constantly adjusting your bathing suit.

The top also features four adjustable straps that help distribute weight evenly across your shoulders. The mid-rise, full-coverage bottoms come in an array of colors and prints.
Helpful review: “I ordered the 2XL and the piece fit comfortably and my boobs were actually supported. It was almost like wearing a sports bra in the pool, but a little less restricting. I thought I would feel really self conscious in this piece, but I wasn't [...] I even did a flip into the pool and nothing popped out or came off.”

This fluttery one-piece swimsuit with ruffle accenting the neckline, back, and cap sleeves is so cute, you’ll want to wear it beyond the pool, too (trust me: no one will know it’s a bathing suit, not a bodysuit). And it’s just as comfy as it is stylish: The V-shaped neckline provides moderate coverage, and removable, molded padded cups offer a push-up effect, without the use of an underwire. The waistband helps keep everything in place, while also creating a defined silhouette. This one also has full-coverage bottoms.
Helpful review: “It is so hard for me to find a top and a bottom that fit correctly. I ordered a size 18 and it fit like a glove. I had some cleavage but it was still modest and I would feel comfortable in front of family. It is so hard to find a bathing suit top I am not spilling out of. I can't wait to wear it, this season!”

The perfect combination of coverage and cleavage, this surplice bikini is stretchy, soft, and supportive.

Plus, an elastic band around the ribcage keeps the top in place and adds extra support. The bottoms are high-waisted, have high-cut legs, and reveal some cheek.
Helpful review: “The unconventional style of the top provides the same support and coverage as a sports bra for women who are well endowed or prefer a modest style, but the V style of the neckline lets you show some cleavage.”
