From website: Our Tankini Swimsuit has a square neckline and removable soft cups with moderate stretch fit with a solid print. WRAP tankini top with high-stretch fabric. The low-rise styling with mid-cut leg openings offers modest coverage. The flattering silhouette boasts cut-out details. Available in vibrant Blue. Size medium would probably fit someone who wears a size small or x-small. It was pretty tight on me and I normally wear a medium in bathing suits. It is beautiful and great quality!
