Cleavage-Enhancing Seaside Bikini Top - Pink Tides
Made for small busts (AA–B cups)
This color way isn't restock- so get it while you can! 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.
Who it’s perfect for
-
Petite chests looking for natural cleavage
-
AA, A, and B cups wanting more shape without padding
-
Narrow rib cages needing a sculpted, supportive feel
-
Anyone who’s never found a triangle top that actually fits a small bust
-
Small-bust shoppers wanting a triangle top that stays put and doesn’t gape
Why small-bust shoppers love it
-
Creates lift without gaping
-
Helps breasts sit centered and rounder
-
Stays in place thanks to the snug, supportive CupUp™ design
-
Booster technology mimics the look of a subtle push-up bra
-
Designed so small chests don’t “slide around” in the cups
-
Adds up to 2 cup sizes of natural-looking enhancement
