Thank you for viewing. The size is unknown, but it was worn from around 3 to 6 months old. It was useful in winter when riding a bicycle with a baby carrier. Since the feet are covered and it has a hood, you don't have to worry about dropping socks or a hat, even when babywearing where you can't see directly, which is reassuring! With rabbit ears and a tail, it's as cute as holding a stuffed animal. I think the white part of the feet shows signs of wear. Please understand and accept that this is a used item before purchasing. I will ship it as simply and compactly as possible.
