Tank style bikini top! Missing all tags, but this is by Tahari--it's their "Standard Wrap Shirred Tankini Swimsuit Top' Vibrant, multicolored abstract pattern with a twist front and shirred/ruched sides. Padded bust with elastic in the lining for extra support. Adjustable spaghetti straps. Aside from missing tags, great condition! Pretty sure it's a medium, and it's stretchy! Happy to answer any questions!🥰
