This is a kimono-style baby outfit. The size is 80. It's made of 100% cotton, gentle on delicate baby skin. It has been worn about twice. It can be used for short outings, small shrine visits, or for older siblings' Shichi-Go-San (ceremony for children aged three, five, and seven). Since it's cotton, you'll need to consider the cold and wear an undershirt or other inner layer. The size is 80, but you can adjust the fit around the tummy area, so it fit my child from 0 to about 2 and a half years old (a small, slender baby). Please understand that this is a used item. Please refrain from purchasing if you are sensitive to this. Please refrain from specifying or consulting about shipping methods or delivery dates. Please refrain from price negotiations.
