25 Swimsuits for Big Boobs That Are Actually Supportive

I’ve spent more time than I’d care to admit in search of the best swimsuits for big boobs, and if you’re reading this, I would imagine that you feel my pain.

Why must it be so difficult?! Traditional “small, medium, large” sizing is an actual JOKE if you’re larger than a D cup. As a 32DD (sometimes 32F) “large” tops might as well be nipple covers on me, so I no longer even bother to try them on.

However, after a LOT of trial and error, I’ve found several brands that design supportive fuller bust bikinis, swimwear with underwire, swimsuits by cup size (the DREAM), D cup swimsuits, and labels that specifically cater to us chesty ladies.

(I also have a post on the best sports bras for large breasts and the strapless bra that changed my life ICYMI!)

The fuller bust bikinis on my list are almost all sized as separates (thank GOD) so you no longer have to worry about whether your top and bottom are the same size. Spoiler alert: they never are.

I also turned to my fellow busty followers on Instagram for their input on swim brands for fuller chests, and I’ve included many of their suggestions here as well. I’ll continue to add to this list as I discover new big boob-friendly brands.

If you’re not sure what specific style is best for your figure, be sure to check out our guide on the best swimsuits according to your body type!

The Best Swimsuits for Big Boobs

---

TWO PIECES

1. Monday Swimwear Aruba Top

If you’re in need of swimsuits for large busts, look no further than Monday Swimwear. In fact, this is one of my favorite swimwear brands, which was founded by influencers Devin Brugman and Natasha Oakley after they discovered a need for swimsuits that accommodate fuller chests.

2. Summersalt Oasis Bikini Top

I own a few swimsuits from Summersalt and can personally vouch for how incredible they are. I also love that on the website you can filter based on suits that provide extra “boob support.”

Plus, the fabric of their suits is unlike any other fabric I’ve ever experienced—it’s almost like Spanx material, which means you’re DEFINITELY going to get the support you need.

3. Monday Swimwear Sorrento Top

I know that underwire bras and swimsuits have a not-so-great reputation but I can confirm that this particular top is so comfy. I love that the material is double lined so the white fabric isn’t see through.

4. ASOS Fuller Bust Bikini Top

I can’t tell you how much I love Asos’ swim selection. In fact, they have an entire category dedicated to swimsuits for big boobs (which you can easily find on their site by clicking here) and almost all of the suits are available in cup sizes ranging from 32DD to 36I.

Not to mention, the bathing suits are a shockingly attainable price. I’m talking under $60. I’ve always associated “cheap” with “unsupportive” but Asos has truly proved me wrong time and time again.

In my experience, the sizing can sometimes be a little off. So I’ll usually order a few different sizes and return whatever doesn’t fit since they have a generous return policy (and free return shipping.)

Who would have thought that Asos would be a treasure trove of underwire bathing suits? Not me.

5. ASOS Mix and Match Bikini Top

6. Wave Babe Cassia Top

I own a similar suit from this brand and can’t recommend it enough (my exact suit is sold out). I wear a size medium. The brand has a variety of supportive suits that also give you an extra bit of lift. It’s worth noting that the bottoms are fairly skimpy, so if you prefer something more full coverage, you might want to size up.

7. Swimsuits for All Bandeau Top

As we know, supportive bikini tops for full chests are hard to come by—especially when they’re strapless—which makes this bikini a godsend.

The bandeau is one of Swimsuit for All’s best-sellers, and it’s so easy to see why. Yet another selling point? The suit is sold as a set, but you can select different sizes for both the top and bottom.

8. Athleta Scoop Bikini Top

Athleta might not be the first place that comes to mind when you think of swimwear, but you can actually find a ton of cute and sporty bra-sized swim options. I also like that they make classic and simple pieces that will stay in style throughout many summers.

9. Freya Jewel Cove Convertible Top

If you’ve ever searched for G cup swimwear, you know that it can be nearly impossible to find. What’s great about Freya is they have a huge range of swimsuits specifically for big busts—G cup included!

The particular style below is a perfect bikini for large breasts because of the convertible straps. They can also be criss-crossed in the back for additional lift and support.

10. Freya Sundance Halter Bikini Top

This is another great style, particularly for women who have a small band size, but a large cup size. I, for one, know that finding a good 32DD swimsuit can be a bit of a challenge.

11. Freya Jewel Cove Bikini Top

I also love the shape of this bikini top. It’s perfect for more active occasions, like kayaking, paddle boarding, or actually swimming. You can buy matching high waisted bottoms to complete the set.

12. Elomi Plus Size Magnetic Wrap Top

I’m also very into the wrap style of this bikini top. It has mesh-lined cups that offer both support, a subtle lift, and flawless shape.

13. Everything But Water Shimmer Bralette Top

Available in sizes 30C to 38G, this cute top has shimmer fabric, adjustable straps, and a double hook back closure (so you know it will stay put.)

14. Swim Systems Maya Underwire Bikini Top

This hot pink swimsuit is so much fun — pair it with a white cover-up or denim shorts as you go from your house to the pool. But it does have an underwire design to offer ample support.

ONE PIECES

15. Monday Corsica One Piece

I swear that this brand has the cutest one piece bathing suits. As soon as I order one, I see another on their website that I want to add to my cart. They’re so timeless, high quality, and have great tummy control. I also own this exact one piece and always recommend it to people.

16. Aruba One Piece

This one piece is truly something you can make your own — it comes in a ton of different sizes and has adjustable bust coverage so you can be in control. Another perk? The fabric is oh-so buttery soft.

17. Summersalt Sidestroke One Piece

I love wearing my Summersalt Sidestroke Swimsuit with a pair of jean shorts, because it actually ends up looking like a really chic one-shoulder top. (If you need help in the shorts department, I also have a guide to the best denim shorts for every body type.)

I also am a big fan of the neckline on this particular swimsuit — no nip slips here!

18. Summersalt Ruched Backflip

This style might have a plunging neckline but the material and design will still keep your girls supported and comfortable. It comes in a few different colors as well as a tropical print (which is so perfect to pack for vacations!)

19. Summersalt Ruffle Oasis

The built-in soft cups on this find create the ideal compromise for those who don’t love an underwire swimsuit but need some extra support. The ruffle detailing on the shoulder straps also add such a sweet and feminine touch.

20. Sunsets Marion Maillot One Piece

Find a better swimsuit for a Hawaiian vacation, I’ll wait. It has molded cups and a bandeau style fit that will keep everything in control while you’re swimming, paddle boarding, or just lounging under the sun.

21. Monday Swimwear Maui One Piece

It doesn’t get more classic than this understated yet sexy black one piece. The structured silhouette and high cut leg design would look so flattering on a variety of body types.

22. Freya Sundance Tankini Top

If you need extra support in the boob department, don’t sleep on tankini tops! By design, they offer more coverage and there are a ton of cute options out there.

23. La Blanca Island Goddess One Piece

With over 500 4.5-star reviews, this one piece from La Blanca is a no-brainer if you’re looking for a simple swimsuit. Reviewers note that it has a highly flattering fit and say that it’s a great basic to have in your closet. I personally am a fan of it because it would go well with anything (making it the ideal swimsuit to pack for a trip).

24. Miraclesuit One Piece

Searching for the best swimsuits for large breasts that are also super flattering? Good news: This pick from Miraclesuit fits the bill.

25. Summersalt Marina One Piece

Swimsuits for big busts don’t have to be boring — this one is so vibrant and comes in a ton of fun colors (and leopard print!) It would also look super cute with a plain white cover-up.
