These are cut-and-sew tops in sizes 120 and 130. I think they can be worn by children who wear size 120. The main material is 100% cotton for all of them. All of them show signs of wear, and being dark colors, there is some fading and fuzzing, but I don't see any pilling or noticeable stains. I'm selling them because my child has outgrown them. I think they can still be worn! Please understand that these are used items. Thank you. m(__)m
