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.

- Andrea H.Verified BuyerReviewingCleavage-Enhancing Seaside Bikini Top - Tropical PunchI recommend this productRated 4 out of 5 stars3 months agoConfidence restored
I did like this top a lot, however, I was torn about what size to order. I ordered a small as I am in between a 34aa and 34a. The small fit but was pretty snug so I am wondering if the medium would have fit better.
I wish there were more options in tops without the ribbed design. Also, I would order matching bottoms if they had more options. Mid rise full coverage hipster bottoms would be great. I am 48 and do not want my bottom hanging out. Please make more options and I will most likely order. I have never felt more confident in a bikini top.

This is by far the most flattering bikini top I have ever owned. I am so incredibly excited to wear it as much as possible (and trust me when I say I haven't really felt that way before with a swimsuit)! I love that this top gives substantial cleavage but it doesn't look or feel like a push up bra.

These bikini tops are perfectly curated for small chests like mine!!! I’ve always been so insecure and angry about my small chest. For the first time in my life, I felt confident going to the beach. For once, there were no cup gaps, the prints were super cute, and the material itself was sooooo comfortable (wayyyyy more comfy than wearing a bra!!). I love the adjustable straps and the fact that there isn’t a clasp in the back! Those clasps would always fail on me and sometimes even dig into my back after long periods of wear.
This bikini is cute, VERY WELL designed, and a pioneer in swimwear for small chests. I cannot recommend this brand enough. If you’re on the fence because of the price, please understand that these swimsuits are built to last, specifically tailored for our body type, and give you confidence that you never knew was possible.

The first ever bikini to give me cleavage! I’ve always felt so insecure at the beach, but I finally felt confident and comfortable in my own body. The print is adorable and I’m so glad I found something that fits me so well ❤️
I originally bought the wrong size, but when I sized down it fit me like a glove!
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.
