28 Swimsuits for Big Boobs That Are Actually Supportive

the best swimsuits for large chests

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 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 boob-friendly brands.

FYI: A lot of these suits are currently on sale right now – be sure to check out my list of the best Memorial Day sales if you haven’t already!



I own both of these swimsuits from Summersalt and can personally vouch for how incredible they are. I 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.

[You can use the code LINDSAY10 for $10 toward your purchase at Summersalt.]

I can’t tell you how much I love Asos’ swim selection. 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 CHEAP. I’m talking under $50. 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.

This brand was started by influencers Devin Brugman (pictured below) and Natasha Oakley, after they discovered a need for swimsuits that accommodate fuller chests and girls with curves.

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 (and it’s matching shirred brief bottom) are one of Swimsuit for All’s best-sellers, and it’s east 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.

I currently own this suit in 3 colors and can’t recommend it enough. I wear a size medium. The fabric gives you the extra lift and support that you need. It’s worth noting that the bottoms are fairly skimpy, so if you prefer something more full coverage, this might not be the suit for you.

    As a fellow 32F, let me just say thank you a million times over for this post. I loved seeing all of the different brands and styles you listed! The Bare Necessities site you linked for the Freya suits is my go-to. An excellent selection at reasonable prices. Pretty much a miracle for small band/large cup size!

    Finally! Someone who feels my pain as a 32DD. Loving this list. I just got an ASOS one piece and I can’t believe it actually fit both my boobs AND my torso. That never happens. If anyone’s looking for just bikini tops, I’ve found good ones at Aerie that have my size plus support (just don’t try the one pieces).

      isn’t Asos the craziest hidden gem EVER?! so good to know about Aerie. Hadn’t even thought about them for busty swim! Going to add to the list + try some for myself!
