This bathing suit is just SO DAMN CUTE! This one piece kids suit has adjustable spaghetti straps and a mesh skirt overlay, all in white/black crescent print. The back features several straps across for a fun detail. Spandex/lycra blend. My daughter Zara is 5 years old, wears a size 6 Years typically, and the swimsuit is slightly large on her. If in between sizes, size down.
