Sleeper I used this when my child was wearing size 90 clothing, so it was a bit large. I think it's probably around size 100. Photo 5: This is a reference, layered over size 90 pajamas. (Please note that the pajamas are not included.) It was helpful for adjusting when the back felt a little cold. The crotch can also be buttoned, preventing it from riding up. #HandsPumpkin #Sleeper
