Hi, it's me, a gal with big boobs who f*cking hates shopping for swimwear because so many—and I mean so many—swimsuits fail to offer the support and coverage for people who have a D+ cup chest. Sure, when you Google 'best swimsuits for big busts,' you get some that claim to work, but finding the right fit means you *actually* need to test them IRL, not just go based on the spon-con. (Also, big bust-friendly swimsuits can sometimes lack in the cuteness department, and sue me, but I want it all!) That's why, after years of personally testing and reviewing swimsuits, I have compiled a list of the best swimsuits for big busts that strike a balance between supportive and sexy—and trust, you probably haven't heard of some of these brands.
Just like when shopping for bras, the trick is to find swimwear that provides the lift and shape your boobs deserve, all while keeping the girls under control. What's worse than a nip slip interrupting support? Nothing, honestly! And I don't want that journey for you (trust me, it's not fun), so I took the guesswork out of your shopping experience by presenting all the best swimsuits for big busts, whether you're looking to keep things modest or are all about showin' off some cleavage.
Our top picks:
- Best overall: Lands' End SlenderSuit
- Best on Amazon: Upopby Tummy Control One Piece Swimsuit
- Editor's favorite: Abercrombie Curve Love Wide Strap Underwire Bikini Top
- Most supportive: Sea Level Eco Essentials Cross Front Multifit Bra
- Best one-piece: Hilor Tummy Control One Piece Swimsuit
From sleek one-pieces to barely-there bikinis, we found cute, comfortable, and well-reviewed styles that'll actually provide support and hold your boobs in place. The best swimsuits for big busts were chosen based on style, support, comfortability, popularity, personal recommendations, and so many reviews to put together this shoppable list of the very best for you.
Pros
- Wide range of customizable size options including length, suit size, and cup size
- UPF 50 sun protection
- Included soft cup bra for shape and support
Cons
- Testers noticed that the chlorine resistance feature only held up for about one or two summer seasons
I can't get over how freaking great this swimsuit looks and feels on my body, which is something I never thought I'd say considering how hard it is to find a swimsuit with big boobs. It's also quite *literally* one of the most size-inclusive suits I've come across, as it offers a million different lengths, size, and bust options. But the real secret behind this reviewer-loved one-piece? Land's End's signature Slendertex® fabric that compresses your body so you feel secure and smooth, yet it doesn't affect your comfort level. It's a type of magic I can't put into words, so you're just going to have to trust me and try it for yourself.
- Material: Nylon, Spandex
- Sizes: Body—Regular, Petite, Long, Plus Size, Long Plus; Cup—Regular, D, DD, DDD; Size—4-24W
Glowing Customer Review: "My favorite suit now!! It's very comfortable. The straps and bottom stay in place. It is the most flattering suit I've worn in decades."
Pros
- Super comfortable suit that doesn't ride up
- Compression around the bust area so there's no constant readjusting
- 23 different color options
Cons
- Some testers wish the straps were slightly wider
Amazon testers are brutally honest, so you best bet you'll get the straight-up truth when shopping there. That's why when you see a product with an almost perfect rating from thousands of reviewers, like this swimsuit, you can pretty much bet you've found a hidden gem. I put my faith into the hands of said Amazon reviewers and ordered this swimsuit. One two words: Un-freaking-believable. My boobs have never stayed in place like they did in this suit—I didn't even have to readjust once!
- Material: 80% Polyamide, 20% Elastane
- Sizes: 6-18
Glowing Customer Review: "This is one of the best-fitting swimsuits I have ever tried on- and I NEVER enjoy any swimsuit on me! This is flattering in every way- it covers my large chest so well and it feels so supportive. I literally am going to buy three more!!!! I bought these for my son's swim lessons and it is PERFECT."
Pros
- Great side support/coverage
- Designed specifically for those with cup sizes D-F
Cons
- Some may find the band fit to be too tight
If you have a larger bust and smaller ribcage (hi, it me), this Abercrombie suit is calling your name. Designed for those who wear a D to F cup and have a proportionally smaller band size, this shimmery bb has adjustable tie straps, unlined cups, and an easy back hook detail that I find really key for a personalized fit. Plus, it comes in two shades and matches *perfectly* with the Cinch Tie High-Waist High-Leg Cheeky Bottom.
- Material: Lining:80% Nylon, 20% Elastane / Body:75% Nylon, 16% Elastane, 9% Metallic
- Sizes: 28-42, D-F
Glowing Customer Review: "Thank you, A&F, for finally being a company that thinks about those with larger breasts but smaller rib cage/waist. This is the first bathing suit top that I’ve ever purchased that has actually fit. Purchased the Curve Love Large and it fit perfectly for 38DD."
Pros
- Super affordable option
- Testers love the added ruching
Cons
- Some sizes are often sold out
You don't have to shell out big bucks to get a supportive suit. Enter: this genius one-piece from Hilor, which comes with soft molded bra cups and a twist-front sweetheart neckline that'll keep ya feeling secure all day long. You'll also love the adjustable straps, ruched center panel, and huge variety of color options.
- Material: 82% Nylon, 18% Spandex
- Sizes: 6-18
Glowing Customer Review: "I finally found it! The perfect swimsuit! I especially love the ruching at the waist and the support at the bust. The color is exactly as pictured. The straps are comfortable. My kids even said, 'Great swimsuit, Mom.'"
Pros
- Supportive side boning
Cons
- Some testers note that the boning eventually poked out after wearing it for awhile
Complete with built-in cups and side boning for shape and support, this twist-front top from Sea Level (which comes in half-a-dozen colorways) is such a good choice for folks with larger busts. Other fab features include the supportive powermesh lining, adjustable and convertible straps, and matching Mid Bikini Bottoms—though because of the design and fabric, you can easily mix and match bottoms.
- Material: 85% Recycled Nylon, 15% Elastane
- Sizes: 28-38, D-F
Glowing Customer Review: "Fabulous, so flattering, great look, great fit, and feels very secure. I bought three different colors—favorite top ever."
Pros
- Can be worn as a bodysuit or swimsuit
Cons
- May show "undie" lines if worn as a bodysuit
If you're looking for a must-have basic that can double up as a bodysuit, this is your suit! Available in four colors and either a smooth or ribbed design, this Baywatch-esque suit from Andie offers maximum bust support with its underbust seam, removable cups, and thick cross-back straps.
- Material: 82% Nylon, 18% Spandex
- Sizes: XS-3X
Glowing Customer Review: "I'm very happy with this suit for lap swimming, water sports, or lounging. The fit is good (secure but not uncomfortably tight), the fabric is sturdy and comfortable, the wide shoulder straps are comfortable, and I like the simplicity of the design. The internal bra/cups provide coverage, support, and shape. Pretty much perfect swimsuit."
Pros
- Doesn't pull at your neck, testers note
Cons
- Separate bottom and top adds up price-wise
Another great choice for folks with larger busts is this underwire bikini top from Body Glove, which features power mesh and adjustable two-way back straps to keep your girls in place (and, yep, the matching bottoms are just as supportive). It comes in a huge variety of color options, and don't be surprised if you're tempted to snag 'em all.
- Material: 80% Nylon, 20% Spandex
- Sizes: D-F
Glowing Customer Review: "This is definitely my favorite swim top!" one person writes. "It's hard to find tops that are flattering, supportive, AND comfortable when you have a large chest. The best part is it's not a halter so there's no strain on your neck. I wore this on a cruise and road the Flowrider and it stayed on!!!!"
Pros
- Super compressive (yet comfy!) fit that testers love
Cons
- Some reviewers wish there were more options that just full-butt coverage
The internet-famous Summersalt Sidestroke is beloved for its compressive fit, full butt coverage, and super-flattering diagonal seaming—not to mention its impressive boob support. There's a reason why this suit has earned a cult following, and if you haven't tried it for yourself yet, then the time is now.
- Material: 78% Recycled Polyamide, 22% Elastane
- Sizes: 0-24
Glowing Customer Review: "This bathing suit is EVERYTHING and MORE!" raves one buyer. "I am so beyond happy with my purchase. I was nervous (I am a larger bust and I have never purchased a bathing suit without an underwire) about ordering, but the fit is outstanding, it's comfortable, and I feel confident (even sexy) in it."
Pros
- Side boning creates added security and support
- Material is very thick and not see-through
Cons
- Quite pricey, especially since you have to buy separates
I've been searching for a push-up swim top that makes me feel supported, keeps the girls in the *perfect* spot without overdoing it, and is equally as cute as it is functional. Alas, I was introduced to Montce swim—i.e., the most adorable swimsuit line that flatters my large chest and makes me feel secure. The "Hayden" top is my fave thanks to the wide, adjustable straps and back closure, the cute sweetheart neckline, and the side seam boning for extra security. Oh, and did I mention Taylor Swift was spotted in another style from Montce while vacationing with Travis Kelce?!
- Material: 78% Recycled Polyamide, 22% Elastane
- Sizes: XS-Curve 3
Glowing Customer Review: "Great support for my DD (real) boobs! Love that the straps are adjustable, also. The black velvet is beautiful and thick material, as well."
Pros
- Thick straps offer major support
Cons
- Super deep V that some people may feel uncomfy wearing
There's no denying this one-piece suit from Monday Swimwear is sexy AF. Boasting a deep V-neckline and super-wide shoulder straps, I absolutely love this versatile bb for its adjustable bust coverage and supportive waist panel, which is designed to flatter all kinds of bodies. It's available in black and ivory, and it's well, well worth the investment—trust me, I own it myself.
- Material: 82% Nylon, 18% Spandex
- Sizes: 28-40, A-G
La Blanca Island Goddess Multi-Strap Cross-Back One-Piece
Pros
- Holds its shape
Cons
- Criss-cross straps in back create some funky tan lines
It doesn't get much better than this big bust-friendly one-piece from La Blanca. Available in tons of bright colors, this suit features a sexy plunging neckline, removable cups, built-in tummy control panels, moderate butt coverage, and a fun multi-strap cross-back design—not to mention SO many color options.
- Material: 83% Nylon, 17% Elastane
- Sizes: 30-44, A-DD
Glowing Customer Review: "This material is top notch. It doesn’t feel like though it will ever lose its shape," notes one tester. "The front and back give my 36DD chest a lot of support. I’m constantly chasing my toddler on the beach, so I wanted a lovely style but one that’s also supportive of movement—this is it."
Pros
- Lined bathing suit prevents it from being sheer and adds extra support
Cons
- Some testers note that it runs a bit on the smaller side, so you may have to size up
If you're lookin' for the perfect white bathing suit for your bridal festivities or next vacation, check out this one from Good American. From its iconic 'Always Fits' line that was made to adapt to your ever-changing body, this underwire bikini top is available in sizes up to 5XL, features stretchy elastane-blend fabric, and adjustable straps. Oh, and did I mention that you won't have to worry about it being see-through thanks to the lining?! *Drops mic, adds to cart*
- Material: 95% polyester, 5% spandex
- Sizes: XS-5XL
Glowing Customer Review: "Love the piece. Very well-structured. Quality is amazing."
Pros
- Powermesh plus shelf bra create ultra-support on such a low top
Cons
- Those with a larger ribcage may find the under-bust area to be a bit restricting
Say a warm hello to my newest favorite black one-piece in my bathing suit collection: The Vita Marina Curve Strappy Suit from Cosabella, which is a s-t-u-n-n-i-n-g member of the brand's curve line. With a deep neckline like this, it's understandable to think you may be hanging all out, but shockingly, the compression-like suit (that isn't uncomfy!) keeps everything together thanks to the removable soft cups within the included shelf bra that is lined with power mesh. I also really love how it fits my body and its ability to enhance my curves.
- Material: Body: 78% polyamide, 22% elastane; Lining: 84% polyamide, 16% elastane
- Sizes: XS-XL
Glowing Customer Review: "This is my third time purchasing this suit! Just got it in pink and it’s such a gorgeous color! Size medium fits my 34 dd bust and body perfectly. So flattering and sexy!"
Pros
- Support in just about every design feature
Cons
- No options for a different bottom
Wide straps? Check. Removable padded bra? Check. Thick bottom band? Check. This 'kini from Yonique has everything you need to keep big boobs under control—plus, it comes with full-coverage bottoms that feature lattice mesh panels and built-in tummy control, and you can get it in *SO* many color options.
- Material: 82% Nylon, 18% Spandex
- Sizes: 12-22
Glowing Customer Review: "This is probably the perfect suit for plus-size and large-breasted beach enthusiasts. The top straps are adjustable, and the wide bottom band on the bikini top makes the whole bra unit super supportive. I just love it!"
Pros
- Drawstring is customizable
Cons
- Some colors not available in some sizes
Available in basically every color imaginable, this plus-size monokini features a drawstring cutout in the front, as well as wide, adjustable straps and a hook closure in the back to give you better support. And if you're not into the cheeky look, then you'll appreciate the full-coverage bottoms on this one, too.
- Material: 82% Nylon, 18% Spandex
- Sizes: 12-18
Glowing Customer Review: "This swimsuit is the best combination of sexy, secure, and comfortable!" raves one review. "I feel sooo confident in this! Bigger chests will feel supported and secure while still giving you a cute figure and without looking matronly. Buy this!"
How to choose the best swimsuits for large busts
Just like when you're shopping for any type of bra, you want to think about how much support you'll need and what kind of activities you'll be doing while frolicking on the beach or at the pool. A few things to keep in mind as you shop:
Consider the style
While compressive swim tops (which work by pressing your breasts firmly to your chest to restrict movement) may work well for smaller chests, those with a larger bust should ideally look for swimsuits with built-in cups that separate and hold your boobs in place. Oh, and if you want to support and lift, then it's best to find a style with an underwire, which helps to create a perkier silhouette.
Check out the straps
Straps are key when it comes to support, and typically, a thicker strap means more stability and less movement (not to mention that thinner straps are far more likely to dig into your shoulders or neck). If you have a bigger bust, then you probably also want to look for straps that are wide, adjustable, and—ideally—convertible, so you can customize your fit and make sure they stay firmly in place.
Find the right fit
Shopping for swimwear online can be tricky, especially if you're someone with big boobs. While browsing, consider whether you'd like a compressive or more relaxed fit, then read reviews to see if you should size up, down, or go with your regular bra size. The best swim tops and one-pieces tend to be those that are fully adjustable so you can customize your fit as needed (which is especially important if you're someone with a larger bust and smaller ribcage).
