Made for small busts (A–C cups)

The Montauk Balconette is our most volumizing, contoured, and lift-enhancing top — engineered for small busts craving shape, definition, and that true push-up cleavage effect.

Traditional underwire bikini tops were never made for petite chests. They dug into your rib cage, gaped at the top of the cup, and created empty space instead of shape. So we rebuilt the balconette from the inside out — specifically for AA–C cups.

⭐ How we re-engineered the underwire — made for small busts by small busts

We created a soft-curve underwire that supports without digging, then layered it with our oval-shaped CupUp™ boosters, sewn directly into the cup.

The boosters add gentle volume where small busts naturally need it, filling the cup without gaps and smoothing the transition at the top edge — so the cup finally sits flush instead of hovering or collapsing.

Instead of a hard wire pressing into your ribs, the Montauk feels cushioned, sculpting, and secure, giving you lift and confidence all day long.

CupUp™ technology provides the look of up to 2 cup sizes of added fullness, all while feeling lightweight and natural on the body.

How it fits

• Runs slightly small in the cup for maximum sculpting

• Most dramatic SABAL lift + cleavage

• CupUp™ boosters shape and center the bust

• Underwire feels comfortable, flexible, and soft at the rib cage

• If between sizes:

  • Size DOWN for a stronger push-up effect

  • Size UP for a more relaxed everyday fit

Expect a rounded, boosted, centered silhouette with a glove-like cup fit — no gaping, no sliding, no empty space.

Who it’s perfect for

• A–B cups wanting more visible volume

• Anyone who has ever gaped at the top of an underwire swim top

• Small busts looking for shaping, cleavage, and contour

• Postpartum moms wanting support + restored volume

• Wider rib cages needing comfort without pressure

• Anyone who loves the look of a balconette bra but wants it in swim

Why small-bust shoppers love it

• Creates true push-up cleavage without padding

• No cup gaping or collapsing

• Soft-curve underwire = comfort with structure

• CupUp™ boosters add natural volume (up to 2 cup sizes)

• Helps breasts sit rounder, fuller, and more centered

• Stay-put fit with no sliding or shifting
