Shop women’s bra-sized and cup-size bikini tops designed to provide a more precise fit than standard small-through-large sizing. Explore underwire, wireless, triangle, halter, balconette, twist-front, and convertible styles in a range of cup and band-size combinations.

Bra-sized swim tops may include features such as molded or removable cups, adjustable straps, J-hooks, power-mesh support, and hook-and-eye back closures. Underwire styles provide added lift and structure, while wireless designs offer flexible, natural-feeling comfort.

Begin with your usual bra size, then review the sizing information for the individual product. Some swimwear brands combine multiple bra sizes into one swim size, so check the listed band-and-cup combinations carefully. Also consider the cup shape, neckline, strap width, closure, and coverage level.

Pair your cup-size bikini top with a coordinating high-waist, hipster, full-coverage, tie-side, cheeky, or skirted bottom. Tops and bottoms are sold separately unless otherwise specified.
