The bicorne hat is a type of headwear that became popular in the late 18th and early 19th centuries. It is characterized by its two points, or "cornes," which extend outward. The hat was often made of felt or wool and was typically worn by military officers and gentlemen during the French Revolution and the Napoleonic Wars. The bicorne is often associated with the iconic figure of Napoleon Bonaparte, who famously wore it tilted to one side. This style of hat was practical for the time, as it could be easily folded and stored. Today, the bicorne is mostly seen in historical reenactments and museums.
