This is a short-sleeved coverall/romper from GAP ☺︎ It looks like a shirt-style all-in-one, and is a stylish outfit that can be worn for 100-day celebrations and other events♪ The size is 6 months to 12 months, which I think is about 80cm! I only wore it twice because my baby was a big baby. The crotch has buttons, making diaper changes convenient! Please only purchase if you understand that this is a used item♡
