HOT ! 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.
