Size: 60-80 My child wore this when they were around size 70, and it fit perfectly. The fabric is relatively thin, so I think it can be worn from autumn to early spring. It's been worn about 5 times, but there is some fuzzing and pilling from washing. Please purchase with the understanding that this is a used item. #Comme Ca Ism #Baby Clothes #Newborn #Coverall #Rompers
