【Ocean Pacific】 Back Frill Rash Guard 2-Piece Set - Charcoal Gray I purchased this from the official website. Since the M size was sold out, I bought the L size. However, it was a bit too big for my height, so I hesitated. But I repurchased the M size when it was restocked. The L size seems to be currently sold out online. It doesn't cling to the body, so I think it's easy to wear. Only tried it on.
