Cleavage-Enhancing Seaside Bikini Top- Sage Ribbed

Cleavage-Enhancing Seaside Bikini Top- Sage Ribbed

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.

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

Sizing Notes

  • XS: AAA–A cups

  • S: AA–A cups

  • M: A–B cups

  • L: B–C cups

If you are between S and M, choose:
