Thank you for viewing. This is a winter hat for babies from BeBe. The size is free. The part with the flower covers the ears, so I think it will keep the ears from getting cold. It can be used from newborns, but it's a little big. Used a few times. There is a little bit of fluffing, but I don't see any stains or snags. From the top of the head to the bottom of the flower → about 20cm From the forehead to the back of the head → about 23cm Acrylic 70% Wool 30% Partial use Acrylic 55% Nylon 30% Wool 15% Made in Japan Home cleaned. The fabric is soft and slightly stretchy. Please refrain from purchasing if you have any concerns.
