The 20 Best Swimsuits for Big Busts, from Skimpy Bikinis to Super Supportive One-Pieces
We’re almost certain that an itsy-bitsy, teenie-weenie yellow polka-dot bikini never held Dolly or Marilyn’s buxom chests in place. And as a modern woman (especially one with an ample bosom), you owe it to yourself to find a swimsuit that’s flattering, supportive and comfortable. And we’ve got some useful tips for finding suits that not only keep you feeling your best for a day at the beach or the pool, but that will prevent you from experiencing any embarrassing nip slips. Look, we’ve all been there at least once and we never want to relive it.
As someone who is a member of the fuller bust society, I have just one major piece of advice that I’ve gathered after years of in-depth swimwear research (i.e., obsessively shopping for a new suit each summer): Bikinis and one-pieces that were specifically designed to fit your bigger boobs are going to be your best friend. That means seeking out brands that offer D+ sizing or only shopping from retailers that include bra sizes alongside their letter sizing. I don’t care if that cute triangle top is worn by every celeb ever and your BFF, if they’re a B-cup and you’re a G-cup, it ain’t going to work because it was not designed with your tatas in mind.
So, before we get into the actual swimsuits, let’s go over the four main styles that will, ahem, suit you best.
1. Underwire: A swimsuit with bra-like underwire is going to offer much of the same support as the lingerie you wear every day. But that doesn’t mean your only option is almost identical to a bra (even if it does fit like one). Plenty of swimsuits incorporate supportive underwire in new and creative ways, like inside wrap tops, tucked into bandeaus and hidden in the shelf of a one-piece.
2. Scoop Neck + Wide Straps: Leave flimsy strings on the shelf. You’ll fare much better with thicker straps that actually provide support, while the scoop neck will show just enough cleavage to maintain a sexy touch without giving away the whole farm.
3. Tie or Cross Front: Tie- or cross-front suits are universally flattering for women of all shapes and sizes. While some options are adjustable, they all tend to have more fabric on the sides, meaning they can easily accommodate larger cup sizes without leading to any side spillage.
4. Halter: The trick here? Find a halter that fits your shape and size. If your breasts sit wider apart or point outward, you’re going to do better with a top that has more coverage on the sides. On the contrary, if your boobs sit close together, you’ll want a top with built-in cups that can both separate and lift.
And now, onto the 20 best swimsuits for big busts
1. Peek & Beau Underwire Bikini Top with Tie Front and High Leg Bikini Bottom
Best Tie-Front Style
ASOS is one of our favorite destinations for trendy, affordable and supportive swim for sizes D and up from a range of brands (including their own). Just a note: The site’s Fuller Bust section tends to sell out fast once summer looms closer, so now’s the time to stock up on cute numbers like this ruffled bikini that’s cute and goes up to a 36H.
Available in size 30E to 36H for tops and 2 to 14 for bottoms.
2. Freya Sundance Underwire One-Piece Swimsuit
Best Illusion One-Piece
Sometimes you’re not in the mood to bare it all in a bikini—but you still want to show a little skin. That’s where this Freya design comes into play. It’s basically a bandeau top bikini with matching bottoms, with a sheer lace overlay that provides an extra hint of coverage. Plus, the sizing is based on your bra size, so it’ll actually work with your bust, not against it.
Available in sizes 30E to 40F.
3. Aerie Waffle Scalloped Bandeau Bikini Top and High Waisted Bikini Bottom
Best Textured Material
Sometimes, all it takes is a heartfelt review to really get the feel for a swimsuit. And that’s the case with this Aerie number, which comes in lime green, peach and black. “By far the best coverage from a scoop/bandeau top from Aerie...Most scoops cover like half a boob but this actually holds you in without any spillage,” writes the shopper, who notes that she’s a 38DD in Aerie bras. Other reviews note that this top fits a bit roomier than they expected, so you might want to go a size down for a snug feel.
Available in sizes XXS to XXL
4. Andie The Amalfi
Best Black Suit
Reviewers love this Andie suit for being both flattering and supportive—and plenty of them are in the DD to DDD range. The sizing goes up to an XXXL and is offered in a long-torso length, so you’re sure to find this suit actually hugs your frame, without suffocating or smooshing it.
Available in size XS to XXXL, and in long-torso.
5. Wild Isles Dottie Tie Bikini Top and Hana High Waisted Bikini Bottoms
Best Keyhole Detail
This swim brand developed a whole new sizing format for tops that work from C to H cups and bottoms range from size 2 to 24. And Wild Isles makes sure to show models in your size on its site, so you can actually get a feel for how these bikinis will look on you. (And if a total coverage, high-cut top is your thing, they’ve got you covered—literally.)
Available in band sizes 28 to 44 and cup sizes C to H and 2 to 24 for bottoms.
6. Panache Anya Spot Underwire One-Piece
Best Retro Style
Ranging from 30D to 40K, we love that this retro chic suit doesn’t look like the rest of the dowdy, supportive one-pieces out here. Plus, that side ruching is going to look so flattering whether you’re pear-shaped or hourglass-shaped.
Available in sizes 30D to 40K.
7. ASOS DESIGN Fuller Bust Recycled Square Neck Crop Bikini and Tie Side V-Cut Bikini Bottom
Best Wire-Free Top
Not a fan of underwire? No problem. This triangle-style top will still fit properly, but it's made without wires for a comfy but sexy fit, going all the way up to size 38I. And it’ll only set you back $20.
Available in sizes 30E to 38I in tops and 0 to 14 for bottoms.
8. Summersalt The Ruched Backflip
Best Wide-Strap One-Piece
If you look at skimpy straps on suits and immediately start rubbing your shoulders due to phantom pain, we feel you. And so does Summersalt, because they designed this cute and sexy one-piece with straps that will evenly distribute the weight of your bust among your whole shoulder...not just a fourth inch of it. Plus, you can hardly tell, but there’s a band at the waist that will totally show off your curves.
Available in sizes 2 to 22.
9. Elomi Plus-Size Magnetic Wrap Underwire Bikini and Bikini Bottom
Best Plus-Size Bikini
Ready to be impressed? This flattering twist-front bikini top features mesh-lined cups with a four-part seam for ultimate lift, comfort and shape. We’re all about that kind of support—especially when it comes with adjustable straps and an easy-to-use snap back closure.
Available in sizes 34E to 44JJ for tops and 12 to 22 for bottoms.
10. Raq Apparel Multi-Way Top and ‘90s Brief
As a fashion editor with big boobs, I’ve long appreciated Raq’s swimwear options that are always stylish *and* supportive. The Australia-based brand recently reworked their fit (so you’ll be a different size in this style if you’ve shopped from Raq previously), but note that going with your regular bra size will result in ample “containment and coverage.” Want a sexier look with more cleavage? Simply go down one cup size.
Available in sizes 30H to 36K for tops and 4 to 12 for bottoms.
11. Athleta Entwined Bikini Top and Clean Full Bottom
Best Overall Support
This top feels like your fave sports bra—but is way more beach-friendly. While the front is full-coverage and cut pretty high, the back has a crisscross detail that looks so cute on the sand. And the whole thing provides more than enough support for you to play volleyball, surf or swim laps.
Available in sizes 32B to 40DD for tops and XXS to XL for bottoms.
12. City Chic Salamis One-Piece Swimsuit
Best Off-the-Shoulder Design
Thought you couldn’t wear off-the-shoulder or strapless styles? Think again. This hot pink one-piece actually has underwire hidden under those cute ruffles and eye-catching hue. It also has a seam at the waist that will work like magic when it comes to flattering your curves.
Available in sizes 14 to 24.
13. L*Space Pointelle Rib Siren Bikini Top and Pointelle Rib Court Bikini Bottom
Best Plunge Top With Support
L*Space offers a selection of their suits in D and DD sizes, including this plunging top that features an underbust seam and strategically placed darting for a truly flattering finish. Says one customer, who usually wears a 36DD and went with a DD in this suit: “I usually have a really hard time finding tops that work for me but this was perfect. The material is really cute and textured. The design of the top is sexy but still works for a larger bust.”
Available in sizes XS to DD for tops and XS to XL for for bottoms.
14. Kitty and Vibe Cut Out One Piece
Best Cut-Out One-Piece
Our fave part about this suit? It’s not the cute (but not too revealing) front cutout or the fact that multiple shoppers say the fabric feels just as curve-hugging as Spanx. It’s the clasp at the back that makes sure your girls stay in place for an entire day at the beach or the pool
Available in sizes S to 3X, and long torso.
15. Wolf & Whistle Underwire Bikini and High Leg Bikini Bottom in Zebra Print
Best Wide Shoulder Straps
As you’ve probably experienced, a halter neck looks great for giving your girls a little bit of a lift—but can leave you with a sore neck if you need to tie it tight. This underwire style still offers plenty of support but has wide shoulder straps that won’t put any unnecessary strain on your upper body.
Available in sizes 30DD to 36I for tops and 2 to 14 for bottoms.
16. Triangl Mica Top and Bottoms
Best for Small Ribcages
This celeb-beloved brand might not be for all gals with bigger busts, but in recent years they have introduced S+ and S++ suits. Those sizes are ideal for those who have a smaller ribcage and a bigger bust—and it’s offered for almost every top in their range. For the most coverage and support, I find the above tank-style top works best (and comes in a ton of different colors, patterns and other finishes you’ll actually want to wear).
Available in sizes XXS to XL for tops and bottoms.
17. Lauren Ralph Lauren Beach Club Solid Twist Underwire Tummy-Control One-Piece Swimsuit
Most Flattering Cut
Based on the name, you might say this suit does it all. And you’re not wrong. It features underwire that’s comfy yet effective, tummy control that’s super discrete and a V-front that doesn’t show off too much skin. Not to mention, this Lauren Ralph Lauren style comes in five vibrant shades and can fit up to a size 16.
Available in sizes 4 to 16.
18. Sunsets Olive Taylor Underwire Tankini Top and The High Road Bikini Bottom
Look, tankinis might not be the trendiest style out there. But who cares about trends when this flowy, bust-friendly top makes you look and feel good? That’s the most important part about finding a suit—and it helps that the built-in foam underwire cups add the kind of life you’ve come to expect from your actual bras.
Available in sizes 32G to 40G for tops and L to 16 for bottoms.
19. Heidi Klein Core Textured D-G U-Bar Top and Fold Over Bottom
Best Ruched-Front Design
Between the trendy ribbed fabric, the shiny gold hardware and the combo of boning and cups, we are truly in awe of this chic suit. Not to mention, that navy blue shade will look good with any skin tone. Yeah, we’ll be wearing this style from Memorial Day to Labor Day.
Available in sizes S to XL for tops and XS to XL for bottoms.
20. Sanctuary Tie-Front One-Piece Swimsuit
Best Patterned One-Piece
This cut might not fly for all cup sizes, but for those who fall in the D to F range, this plunging suit might actually become your new fave. The waist tie will make sure your figure looks its absolute best, while those fully adjustable straps will keep your boobs firmly tucked into place. And how fantastic is that color combo?
Available in sizes XS to XL.
