Costa Top | Tan OasisA bold take on a classic shape: the Costa Top is a supportive, underwire bikini bra top, sculpted update to our signature silhouette. Designed to lift, flatter, and stay put. Triple lined for extra hold with adjustable straps and a customizable band, it's made to move with you while keeping everything in place. Crafted from our signature buttery soft fabric, it offers structure without stiffness and a feel that's as good as it looks. Supportive.
