Man-Hat-On Milliners for Wizards

Man-Hat-On Milliners for Wizards was an American wizarding hat shop offering hats in both wizarding and No-Maj styles. The shop was founded in 1819. Some of the hats they offered included top hats, dobbys, flat caps, panamas, straw boaters, trilbys, and "The Fitzrovian", the latter being a new style of hat from London in the 1920s.
