Before large wigs became popular for men during the late seventeenth century, low-crowned, large-brimmed, plumed, or feathered, hats were worn. As wigs increased in size, plumes disappeared and the brims of hats were cocked up. When the brim was folded up in three places, the hat became a tricorne, a three-cornered hat. Generally dark in color, tricornes were often edged with a gold braided trim after about 1675. Worn with one point forward, the tricorne hat emerged as the most fashionable hat for men in the late seventeenth and most of the eighteenth century. To be most stylish, men cocked, or tipped, their tricornes to one side or another.
