You're looking at used but in good condition, girls size 4T Disney one-piece swimsuit. It has The Little Mermaid Ariel design on the front, and double straps which cross, and it's a shimmery design.  Polyester/spandex mix. There are a few marks/snags on the inside of the bathing suit, which I've tried to take pictures of. There's a small snag on the front which you may not even notice.
