BY Pink Obsession — Signature Beach Club String Bikini Set brings a bold Bikini Yes signature to classic black swimwear. Hot-pink BikiniYes lettering, gold-tone heart artwork and two distinctive statements — Ocean State of Mind on the triangle top and Beach Club on the matching bottoms — create a coordinated look with playful beach-club attitude.
Made for beach holidays, poolside afternoons and resort escapes, this black-and-pink string bikini pairs easily with a sheer cover-up, an open beach shirt or a flowing wrap skirt. Adjustable neck, back and hip ties let you personalize the fastening, while removable top padding and soft, double-layered stretch fabric offer flexible swim comfort.
