‘My highlight of 2015’ — Napoleon’s bicorne hat

Something I didn't know: "Like all of his hats, this bicorne featured an additional felt patch, on the inside of the front brim, design to allow easier handling. It also lacked the leather lining commonly added to hats of the period, as Napoleon was allergic to the material."
