This is a cute knit hat with a pom-pom. This one is for infants (around 1 year old?). The size is indicated as F (free) on the tag (see image four). Because it's made of knit material, it has some stretch and can be used for a long time even as your child grows. It was used about 1-2 times for a short period, and has been stored after being cleaned at home. ☆Please check for stock availability by commenting before purchasing m(_ _)m
