Made for small busts (AA–B cups)
The Seaside Top is our signature cleavage-enhancing triangle bikini top designed exclusively for small busts. Featuring our proprietary CupUp™ booster technology, this style creates natural lift, centered definition, and the effortless “brought-together” shape the IBTC loves.
Unlike traditional swim padding, our lightweight silicone boosters are sewn in — no shifting pads, no gaps, no inserts, just sculpting that feels like you… but boosted. CupUp™ enhances the look of up to 2 cup sizes depending on your natural volume and rib cage shape.
How it fits
-
Runs snug in the cups (intentional — the snugness activates CupUp™ lift)
-
Adjustable straps + fixed band
-
Best for AAA–B cups, petite frames, and anyone wanting extra definition
-
If you’re between sizes → size UP
-
Expect a lifted, rounded, cleavage-forward look
CupUp™ may feel slightly more structured when you hold it, but once on your body, it feels lightweight, secure, and incredibly natural.

AA, A, and B cups wanting more shape without padding

Why small-bust shoppers love it

Stays in place thanks to the snug, supportive CupUp™ design
-

Designed so small chests don’t “slide around” in the cups

Adds up to 2 cup sizes of natural-looking enhancement

I normally go for a 32A in bras, so I don’t have much going on. I ordered a small. But oh my gosh this makes me feel so much better wearing it! I have 2 beach trips planned this year and can’t wait to wear this bikini. I love that the top doesn’t tie, so it will stay put. And I love how adjustable and comfortable it is. I’ll definitely be buying another in navy once it’s available. :)
IT’S NOT YOUR BODY, IT’S THE BIKINI TOP
Sewn-In Goodness
We’ve reimagined bikini inserts to actually work (Goodbye traditional cotton pads!). Our patent-pending silicone boosters are sewn into each top, giving you a sculpted, comfortable lift that feels like your favorite bra, but better.
Your Most Flattering Fit Ever
We know the bikini industry has let the small-bust community down, often sizing "Smalls" for 34B cups. That’s why we’ve tailored our designs specifically for AA to B cups, using real women with small busts to show how they truly fit and flatter. Real small busts, real bodies, real results.
Designed Just For You (AA-B Cups)
Comfortable & flattering cleavage? Yes, please. Our signature fit has nothing to do with changing your body and everything to do with what you already have. Our bikinis give a natural, flattering lift. The rest is all you, just as it should be.
