What's an underwire bikini top?
An underwire bikini top has a thin wire sewn into the base of each cup - same concept as an underwire bra - that lifts and shapes without relying on padding alone. Brands like Damsel and Broken Promises use this construction in polyester and nylon blends that hold up in the water. It's a structured alternative to triangle or bandeau styles if you want more definition and support.
How are underwire bikini tops supposed to fit?
The wire should sit flat against your ribcage and follow the curve of your bust - if it's poking or floating away from your skin, size up. The cups should fully contain your chest with no spillover or gaping. Straps should feel snug but not dig in; most styles come with adjustable straps so you can dial in the fit.
What size scale is available for underwire bikini tops?
Most underwire bikini tops at Zumiez run in standard XS through XL sizing. Check the individual product page for the exact size range since it varies by style and brand. When in doubt, size up - underwire tops with less stretch in the fabric tend to run snug.
