Both items have no brand tags or care tags. 100% cotton. I think the romper was size 80. I dressed my child in the shorts around the age of one. Both have strings at the waist that can be tightened. They were purchased separately, so they are not exactly the same, but they have similar colors and feel. There are no noticeable stains or pilling, but there is a feeling of wear and tear from use. Please purchase if you understand that these are used items stored at home. Korean children's clothing.
