“...the ‘Make America Great Again’ campaign hat first worn in July by Donald J. Trump in Laredo, Tex., and since spotted on hipsters from Williamsburg, Brooklyn, to the Silver Lake district of Los Angeles and in the football locker of Tom Brady, not to mention on the heads of the hundreds of Trump loyalists at his rallies. ‘I was certainly surprised to the extent it caught on,’ Mr. Trump said in a phone interview last week. ‘It’s become the hottest fashion item there is.’ The New York Times declares a hat to be the accessory of the season.
