Baby's ceremonial suit (rompers)! Size 70. I dressed my baby in this when we went to a wedding. It's integrated with a vest, and has snap buttons for easy diaper changes. The collar (front collar area) is slightly yellowed, but I think it's not very noticeable in person. Please check the photos. How about it as an outfit for celebrations or commemorative photos? Please refrain from purchasing if you are sensitive to used items. Immediate purchase is OK!
