I think it's probably only been tried on. I've looked it over and don't see any noticeable stains or anything, but I apologize if I've missed anything. Size is S (1-2y) I've included photos with a measuring tape, so please use them as a reference. No box. This is Korean children's clothing, so the quality standards are lower than those of Japanese products. *Please check my profile and purchase only if you agree to the contents. #BellcoroKidsAccessories 220
