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.

Fabric & Details

Crafted from a luxurious Brazilian jacquard swim fabric, this Seaside Top features a subtle woven texture that adds dimension, richness, and an elevated feel to this signature silhouette. The textured fabric catches the light beautifully while maintaining the smooth stretch and comfort expected from premium swimwear.

Elegant hammered gold ring hardware at the straps adds a refined, jewelry-like detail that gives this bikini a sophisticated upgrade — the kind of subtle luxury that makes the suit feel special the moment you put it on.

Because this is a delicate jacquard weave, we recommend treating it with a little extra care.

Care Notes

• Avoid rough surfaces such as pool edges, stone, or concrete
• Use caution around hot tubs, velcro, or abrasive textures
• If minor fabric pulls occur, a gentle fabric shaver can easily smooth them

This special fabric is chosen for its beauty and texture — and with proper care, it will remain stunning season after season.

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
