This is a one-piece swimsuit for 12-18 month olds, featuring a pink striped design with ribbon and flower decorations. I'm not sure of the Japanese size, but I've listed it as 70cm, although it might be 80cm. My daughter wore it once for a short time in our home pool when she was 1 year and 4 months old. It has a ribbon on the back and is very cute ^ ^ Please consider this item as used and stored at home by a private seller.
