It's very small! I bought it so that I could keep one and give one to a friend. They fit tightly on both of us, seems like it's meant for a child sized head. Also! In the photo, the ears look like they have a posable wire in them (which are normally in these types of headbands to keep the ears up), but in actuality they do not have anything and just flop right down. They are a super cute concept, but the flaws are really disappointing.
