This is a winter floral jinbei featuring SOU・SOU's iconic design. It can be worn over pajamas or everyday clothes for going out. It's approximately size 90, but since it can be worn over regular clothes, my child wore it for one season, starting around 18 months old. It's made of cotton, so it's very comfortable and warm. There are no noticeable stains, but please refrain from purchasing if you are overly concerned about minor imperfections.
