This child's Birthday Shimamura Knit cap with pom-poms Hat Baby Boa Knit hat Color: Beige Size: Free Although there is no size listed, based on the size of hats I already own, I believe it is around 44cm-48cm. As shown in photo 5, the inside back has elastic, so it will stretch a little. I purchased this when my child was about six months old, but they only tried it on at home and never wore it outside. It is new and unused, but please understand that the tag has been cut off and it has been stored at home. When shipping, it will be folded and slightly compressed.
