Our adult size costume skimmer hat is made of tan straw and topped with a red and black striped grosgain ribbon band with a dapper bow on one side to complete your look for that 1920s costume party, theatrical role, or performance as a member of a barbershop quartet. The inner circumference will fit a head size of 23 inches or less (fits most adults). We also have foam hat sizing to adjust the size down if you need it to fit a smaller head!
