This is a vintage 1950's bathing suit. Feels like a cotton or cotton blend. Label is Sea Waves. Blue with pink, green and blue floral pattern. Green straps that button at back. It does have little belt loops on either side. They can be removed without harming the garment. This is completely lined with built-in bra. The lining is clean with no issues. Tag says 16 but this is vintage. Please lose the measurements. I would call it a size medium. Fits up to a 38" bust, 30" waist and 38" hips. Very good condition with no rips, tears, stains or holes.
