The listed size is 100, but since my child used it in early and mid-kindergarten, it could still be worn even if the child was around a size 110. (Individual differences may apply) My child used this at kindergarten, so there are stains around the stomach and sleeves. The third button from the top has some fraying, but the button can still be used. *Please refrain from purchasing if you are sensitive to used items. Thank you for looking! ⭐
