☆ The red romper on the left is size 66. I think it can be worn by children who wear sizes 60-70. I put it on my child who was born in January, and it was fluffy and warm (*^^*) The zipper is also protected at the neck, so it was safe. ☆ The romper on the right is size 50-60. Both were worn a few times and then outgrown, so there are no noticeable stains.
