I bought this hat for an easy Halloween costume to pair with a tuxedo. This tops the outfit perfectly. The hat easily fit my adult head size with enough room to tuck all my thick hair underneath.  It's a plush material like a stuffed animal, not high quality fabric by any means-- but it would be silly to expect that for the low price. This will work perfect for my costume and is cute enough to keep for winter use, as it does keep me warm with the long side flaps covering the ears.
