I wore this outfit three times: when I was discharged from the maternity hospital, for the baby's first shrine visit, and for my sister's Shichi-Go-San (ceremony for children aged three, five, and seven). It was so cute. The inside is a romper. The material is a little thin, so I recommend wearing undergarments that don't show through easily. The hat matches. Because it's a foreign product, it's hard to tell in the photos, but the strings on the left and right are slightly different lengths. The size is listed as 80, but I think it runs a little small. Length (front) approx. 42.5 cm Width approx. 27 cm (Back) approx. 40 cm I don't think there are any noticeable stains, but it has been stored at home, so I would appreciate it if you could understand.
