September 15, 1922 –
According to fashion arbiters from days gone by – you should not be wearing your straw hats any longer this season –
In the early 20th Century, tradition held that a man switch from straw hats to felt ones on September 15th. If he wore “the taboo headgear” after that date, hooligans were free to smash it to bits.
In 1922, a group of men and boy, 1,000 strong from the Five Points neighborhood sparked a bizarre riot that shook New York City from the Battery to the Bronx, as they prowled the city, beating men, who refused to remove their straw hats.
