One Piece Swimsuits for Big Boobs That I Love
Direct links to shop are listed below. For sizing reference, I am typically a 14/16, my bra size is 36J (UK) and I’m 5’8. If you have any questions, feel free to message me on Instagram! I’m always happy to help and want to make sure you find the best supportive one piece swimsuit for you!
Summersalt One Piece Swimsuits
I love Summersalt swimsuits for dozens of reasons. They have quickly become my to brand for one piece swimsuits that fit all my curves! Plus, the bright colors are to die for.
Before I forget, code Casey10 will save you $10 on any Summersalt purchase!
A few things I love about Summersalt… They use recycled materials to create their fabrics, as well as product packaging. They took over 1.5 million body measurements from 10,000 women to get the best fit possible for their swimsuits. The customer service is fantastic (coming from personal experience and hearing stories of other women’s interactions). It truly is designer swimwear without the price tag.
My favorite Summersalt one piece swimsuit for big boobs is the Marina, followed by the Sidestroke. I also have the Ruffle Sidestroke, Wrap One Piece and Swan Dive.
The Marina style has adjustable straps and soft cups. It is $95 before the Summersalt discount code being applies. I am wearing a size 14. It is available in sizes 2-22.
The Sidestroke support comes mainly from the swimsuit’s compression. I am wearing size 14. Depending on the colorway, this Summersalt swimsuit is available in sizes 0-14 or 0-24. It is $95 prior to the discount code.
If you find a swimsuit from Summersalt you like, you can use code CASEY10 for $10 towards your purchase.
Bravissimo One Piece Swimwear
I have been buying lingerie from Bravissimo for a few years now, but summer 2022 was my first time diving into their swimsuit options! I found a few gorgeous one piece swimsuit options for fuller busts. As of now, they’re still available (and some on sale). I’ll keep an eye out for new 2023 swimsuits, too!
This Santa Maria One Piece Swimsuit screams southern belle to me. It’s weird because I don’t consider myself southern whatsoever, but I’m drawn to this blue gingham print swimsuit. It also comes in a very classy black!
Swimtimates Bodysuit doubles as a swimsuit and bodysuit! While I actually wear a lot of swimsuits as bodysuits, this one was created intentionally with that design. I love wearing this swimsuit while swimming laps and being active in the water.
Marbella One Piece Swimsuit is one of the sexiest swimsuits I have in my closet. I love the cut out details, the support that comes from the underwire cups and the little details that really elevate this one piece.
Eloquii Plus Size One Piece Swimwear
While I absolutely love Eloquii for plus size swimsuit options, I have historically struggled with one piece swimsuits that are fuller bust friendly. This season I’ve had had a chance to try a few styles, and a pleasant surprise, they both work! These swimsuits are super stylish options for your next beach vacation or girls trip, but I can’t say they scream “family day at the pool” or “diving board competition swimsuit”.
If you want to feel super fabulous, you can try the One Shoulder Cascade Ruffle Swimsuit from Eloquii. It’s available in sizes 14-32 and comes in 2 different patterns/colors. I am wearing a size 14 in Grape Juice.
This One Shoulder Cutout Detail Swimsuit screams “give me frozen drink and the beach stat!”. This plus size one piece swimsuit is also available in sizes 14-32 and 2 patterns. I am wearing size 14 in Rio Garden. If you are in between sizes, I might suggest going up instead of down in this one. The size works for me, but it is just a bit short in the length which could be beneficial to have a size up.
Andie One Piece Bathing Suits
Andie Swim is an online retailer with staple swimsuit styles that they release in various fabrics, colors, etc, in both bikini and one piece styles. Sizes range from XS-5x, depending on the exact suit. The price point is around $100 for a suit, but it its something high quality that you’ll be able to wear for multiple years.
The Malibu style swimsuit is what I’m wearing above, and I could not sing it’s praises more! I have it in the Luster fabric and a size XLT (tall). But from what I have read, I think in the regular fabric I would need to size up because it has less stretch. This Andie swimsuit is available in sizes XS-XXXL.
A few other one pieces for big boobs that caught my eye are: The Jetties, The Amalfi and The Tulum.
Less Than $40 Amazon One Piece Swimsuits
I have tried so many one piece swimsuits from Amazon over the last few summers… It’s been hit and miss if we’re being honest. However, with that said, I know spending $100 on a nice swimsuit isn’t in the cards for everyone, so I wanted to give Amazon swimsuits a fair try to help you figure out which might work for you! The styles below are my top favorites, but there are more reviews on my blog (links above!).
The criss cross black one piece is under $35, available in sizes 4-18 and 40+ color variations. I am wearing size 14. It fits well, but is a little shorter in the torso than I would ideally like.
I absolutely adore this Amazon one piece swimsuit with criss cross detailing on the side. This one is $27, available in sizes XS-XXL and 14+ color variations. I am wearing the XL.
This Amazon one piece swimsuit screams “bride to be” for me! Of course it does come in other colors if white isn’t your favorite but you have an affinity to mesh cut out swimsuits. It’s available in sizes XS-XXL and 12+ color variations. I am wearing XL.
This cut out swimsuit wasn’t my favorite at first, but after I wore it on the beach, it became one of my favorite supportive one piece swimsuits from the season. It’s available in sizes L-XL / 14 Plus-24 Plus and 20+ color variations. I am wearing XL.
Walmart One Piece Bathing Suits Less Than $30
My Walmart swimsuit order is slowing but surely coming in, so give me a minute to get photos in everything! In the meantime, I did a quick try on over on Instagram and everything is linked below.
How chic is this black one piece! I l love the shirred waist detailing, v cut out and adjustable straps. I do wish the boning was a bit stronger because the straps dig in a tiny bit trying to support the chest. Black V Wire Shirred One Piece Swimsuit comes in sizes S-3X and is $25. I am wearing size XL.
This strappy v neck swimsuit is adorable on! My only personal issue is that it hits me weird on the hips, so I just shimmy it up to create the look of a higher cut leg. Keep in mind that I haven’t worn this one swimming yet, so I can’t speak to it fully if the girls stay in it or not. But with trying it on and dancing around, I don’t experience spillage or runaway boobs. The V Strappy Front One Piece Swimsuit is available in sizes S-3X for $25. I am wearing XL.
The thick band hitting right under your bust is the perfect way to sneak in some bust support without dealing with underwire! The straps are adjustable and I don’t personally find any spillage with the top. You can find the Seersucker Stripe One Piece Swimsuit in sizes S-3X for $25. I am wearing XL.
I can’t wait to get the Solid Plunge V Neck One Piece Swimsuit in the mail this week! It comes in sizes S-3X and is $27. I ordered XL.
Bare Necessities Bra Sized Swimsuits
If you’re looking for bra sized one piece swimsuits, a great place to start your search. is Bare Necessities! Plus you can get a nice discount by signing up for their newsletter. Bare Necessities carries fit focused brands that I love including Elomi, Fantasie and Freya. While I haven’t tried them for myself, I’ve heard great things about Pour Moi and Panache when it comes to one piece swimsuits for big boobs.
This Plus Size Bazaruto One-Piece has soft cups and thick, adjustable straps, making it a great both great one piece swimsuits for big boobs! It is wireless, so while knowing your bra size is still important, it’s not as crucial with this style.
HerRoom Bra Sized One Piece Swimsuits
HerRoom is an online retailers that carries lingerie, shape wear and you guessed it, swimwear! When it comes to one piece swimsuits for large breasts, you can find brands including Curvy Kate, Elomi, Freya and Fantasie.
The Fantasie Palmetto Bay Underwire Swimsuit is a favorite of mine. While this pattern is from 2022, it’s still available in some sizes at HerRoom. If it ends up selling out or it isn’t available in your bra size, you can find the same style in lots of prints.
You can also find the Elomi Bazaruto One-Piece swimsuit at HerRoom. I always suggest checking multiple retailers if one is sold out of your size in the color you prefer, or if one is offering a sale, etc.
This Curvy Kate Holiday Crush Non-Wired One Piece Swimsuit is one of my favorites that you can find at HerRoom. It is bra sized but it does not have underwire in it.
Anne Cole One Piece Swimsuits
Towards the end of summer 2022 I discovered Anne Cole swimsuits. I found a few styles that I really liked, but I haven’t had much of a chance to wear test them. The sizing is a little all over the place, too, just a heads up!
This green zebra print one piece swim has pretty good booty coverage, adjustable straps and a little v neck detail. I am wearing 18W. It comes in plus size and straight size.
The Vintage High Leg Maillot One Piece is a lower support option, but still one I found myself drawn to. The straps are adjustable, the booty is cheeky and the legs are high cut. I am wearing a size 16.
This Anne Cole Square Neck Shirred One Piece is a favorite with my TikTok community! I understand why… A good square neck swimsuit is hard to come by. Add a bold color, adjustable straps and a shirred waistline, we’ve got ourselves a winner. I am wearing size 16W. You can shop it in straight sizes and plus sizes.
Honorable Mention One Piece Swimsuits for Fuller Chests
I can’t say these brands are going to provide you with win after win when it comes to finding one piece swimwear for large busts, but I have found some great options worth sharing!
Old Navy One Piece Swimsuits
I have found one swimsuit style that I am loving so far this year, but I am leaving this as an honorable mention brand because I haven’t historically had a lot of luck with Old Navy one piece swimsuits.
I ordered an XL in this belted one piece and it fits really nicely. It’s got enough length in the torso for me and provides the coverage I need to support my curves. It’s got a shelf bra for light bust support. Note, the straps are not adjustable with this one piece. This crochet one piece swimsuit also has a matching sarong that you can order. The sarong also looks great with white and black swimsuits, so you can elevate that cost per wear a bit.
TA3 Shaping Swimsuits
I’m still trying to figure out. my sizing in TA3. Once I figure that out, we’ll be able to decide if it’s worth the investment!
Show Me Your Mumu One Piece Swimsuits
Aerie One Piece Bathing Suits
To be totally honest, there aren’t a lot of Aerie one piece swimsuits I’ve found that work for big boobs. With that said, one of the most popular swimsuits I’ve ever shared is a wrap swimsuit from Aerie. Quality over quantity with this one! Stay tuned for what styles get released this year.
I wore the Show Me Your Mumu Wifey for Lifey (XL) and white scrunch (XXL) one piece swimsuits in Cabo for our wedding. Neither were amazing support, but both had plenty of coverage for my chest.
Baiia The Label
The only reason I’m labeling the Baiia reversible wrap suit one piece an honorable mention is because I haven’t done a wear test yet. The coverage, compression and fit are great… So fingers crossed it wears just as well as it feels at first try on!
Soma One Piece Swimwear
2022 was my first summer trying on Soma swimsuits and it was both a hit and a miss for me. I tried a bikini that my boobs flew out of, but had better luck with one pieces! I’ll keep an eye out for 2023 one piece swimsuit options and keep y’all posted!
