This is a kids' swimsuit set. It's a bit large for 66cm and 90cm sizes☆ My 1.5-year-old and 3.5-year-old children wore them. (Please use this as a reference only, as children's sizes vary.) They were used infrequently, so I believe they are in good condition. I had an iron-on name label on the tag, so I plan to cut off the tag before shipping.
