This vintage 1950s women’s swimsuit by Phan-Tan is a rare mid-century find. It is a classic black one-piece with adjustable halter straps, button details at the bust, and ruched sides for a flattering silhouette. The suit features the exclusive built-in Phan-Tan girdle support, designed to “help you look better, feel better, swim better.” It has elastic leg openings and a rear zip closure. The swimsuit is in good condition with light wear consistent with age.
