From the brand: 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.
