This is a baby dress that you put on over the existing clothes. You just put it on over what the baby is wearing, so it works with both short sleeves and long sleeves. It's suitable for all seasons. It was worn only once for the Hatsumiyamairi (Shinto shrine visit for newborns) and has been stored at home. Please understand that this is a used item. Please refrain from purchasing if you are very particular about the condition. The length is about 52cm.
