Push - Up Montauk Balconette Bikini Top- Fiesta Shimmer
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:
