A trilby or trilby hat is a soft felt men's hat with a narrow brim and a deeply indented crown. It is traditionally made from rabbit fur felt, but may also be made of other materials such as tweed.
Trilby hats are softer than Homburgs, and have a flexible rather than curved brim. They are also similar to fedoras, but with a narrower brim. The term Trilby is sometimes broadly used to refer to any similar hat, such as the pork pie hat.
Its name derives from the play based on George du Maurier's 1884 novel Trilby. A hat of this style was worn on stage during its first London production.
