pom pom beanie
A type of beanie with a pom pom attached to the top for fashion reasons. The two most common variations (which are affected by wearing, as noted in the beanie wiki) are a pom pom that sits directly atop the beanie and one that hangs loosely to the side, reminiscent of a santa hat.
May be combined with earflap beanie.
