One Size. Shelf Bra Support. Navy That Goes Everywhere, Does Everything. The Anne Cole One Size Fits Most Navy Tank One Piece Swimsuit is the one-piece that fits sizes 4–14 in a single, seamlessly constructed piece — with everything you need built right in. A built-in shelf bra provides additional support and shape, giving you the confidence of a structured one-piece without any underwire or rigid construction. A seamless design eliminates any lines, edges, or pressure points, wrapping the body in a smooth, second-skin construction that moves with you effortlessly.
