A tricorn is a type of hat that was popular in the 18th century, characterized by its three pointed brims. It was commonly worn by men, especially among the upper classes and military officers. The tricorn is often associated with the American Revolution and the French Revolution, symbolizing the fashion of that era. The hat is typically made from materials like felt or wool and can be adorned with ribbons or feathers. While it fell out of fashion in the 19th century, the tricorn remains a recognizable symbol of historical attire, often seen in period films and reenactments.
