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 1. Both have drawstrings at the waist. I bought them separately, so they are not exactly the same, but the colors and feel are similar. 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.
