Finally, Cute (and Comfy) Swimsuits for Bigger Boobs

If you have a bigger cup size, finding your dream swimsuit is a pursuit you may have given up on long ago. From flimsy bikini tops (and the perils of nip-slips) to the dreaded side-spillage — it’s a familiar refrain for those of us with bigger busts. 

But there’s hope yet. The swimsuit gods are shining their light down on us this summer with the advent of Knix Swim 2022. Sure, we might be a bit biased, but in the words of modern-day philosopher Julia Fox, it’s a masterpiece if we do say so ourselves.

To be clear, we keep breast size and support in mind when designing all of our swimsuits — which is why our standard sizes range from XS to 4XL (A-cup to D-cup). Beyond that, most of our styles feature plus-cups for the E-cup to G-cup range. 

Behind the scenes, our all-star design team has tested and fit each collection item on real people (revolutionary, we know). Our philosophy? Swimsuits shouldn’t just look cute, they should support and move with you as you run, jump, and frolic on the beach Baywatch-style (but with a fraction of the bounce). 

With that, here’s a look at some of our favorite bust-friendly swimsuits for the summer season. 

Classic One Piece

You can’t go wrong with a quintessential one-piece swimsuit — it’s basically the bathing suit equivalent of a LBD. Chic with clean lines and the perfect amount of coverage (and cleavage!), our Classic One Piece has built-in bust support and adjustable straps that shape and hold.

One Wave One Piece

This asymmetrical, one-shoulder look is everything for summer. When it comes to the One Wave One Piece, all you have to do is slide on some daisy dukes, a Relaxed Fit Beach Shirt, some shades, and you’re set for the season. While the strap isn’t adjustable, you can count on loads of built-in support and just the right amount of coverage.  

Sunset Wrap One Piece

This little number is another classic — but with a twist. The body-hugging silhouette and deep-V neckline of the Sunset Wrap One Piece are accentuated by its waist-wrap embellishment. On top of making you look snatched, the waist-wrap provides extra support and adjustability.

Puffy Sleeve Bikini Top

Serving major Bridgerton vibes is our Puffy Sleeve Bikini Top. Wear the sleeves up or off-the-shoulders — and maybe paired with a pair of Ultra High Bikini Bottoms while you’re at it. However you choose to style it, you can count on unparalleled support so you can focus on being radiant. Duh

Sunny Scoop Bikini Top

She’s sporty, yet dainty; supportive, yet cleavage-baring — she’s our new Sunny Scoop Bikini Top. The ultra-flattering scoop neck is a match for the built-in support, sturdy underband, and adjustable straps. It’s our take on the classic bikini top, but with ample side coverage and lift for all bust sizes.

One Wave Bikini Top

We said it once and we’ll say it again: we’re living for the single-strap trend. A far cry from a flimsy bandeau, our figure-hugging One Wave Bikini Top packs a surprising amount of support (and style). 

Tankini Bikini Top

For a bikini that feels like your favorite form-fitting tank, look no further than our Tankini Bikini Top. The extra wide underband provides extra bust and tummy support, while the adjustable straps allow you to personalize your fit. Its V-neck silhouette isn’t quite as plunging as it was in last season’s collection (we took your feedback!), striking the perfect balance between coverage and cleavage.
