I bought this because it's cute, but my child doesn't like hats and wouldn't wear it, so they outgrew it. The size is suitable for around 1.5 years old. Head size varies, so please use this as a reference. It's originally a used item, but it's in a clean condition with no pilling. There's some stretching, but not enough to significantly alter the size. Please understand that this is a used item before purchasing! I will ship it compactly, so please understand that as well!
