Made for small busts (AA–C cups)

The Hamptons Triangle Halter is our most adjustable small-bust bikini top — designed by small-busted women, for small-busted women. Traditional triangle tops slide, flatten, and offer zero support, which always made wearing them feel intimidating if you didn’t have cleavage to hold the shape.

So we redesigned the triangle top from the inside out.

We locked the center front, so the triangle cups stay in place instead of sliding outward and flattening your chest. Combined with our sewn-in CupUp™ boosters, the Hamptons gently lifts, centers, and adds the look of up to 2 cup sizes — giving small busts the shape and confidence that traditional bikinis never could.

This is the first triangle top many of our customers say they’ve ever truly felt confident in.

How it fits

• True to size with fully adjustable neck + back ties

• CupUp™ boosters lift and center the bust without padding

• Locked center front prevents flattening + sliding

• If between sizes → size UP for comfort

• Expect a soft, rounded, sculpted, customizable lift

CupUp™ may feel slightly more structured in your hands, but once you tie it on, it feels lightweight, supportive, and incredibly natural.

Who it’s perfect for

• AA–C cups wanting adjustable lift

• Small chests that have never felt confident in traditional triangle tops

• Petite busts that slide around or flatten in regular bikinis

• Wider rib cages or postpartum bodies who need flexibility

• Anyone wanting natural lift without push-up padding

Why small-bust shoppers love it

• Finally—a triangle top that doesn’t flatten your chest

• Locked center = cups stay centered (no sliding outward)

• Creates cleavage without gaps

• Lightweight CupUp™ boosters add up to 2 cup sizes

• Helps breasts sit closer together + rounder
