Trilby is an English gender-neutral name that means "From Thorolf's Farm". The name is derived from the stage adaptation of George du Maurier's 1894 novel Trilby, where a hat of this style was worn in the first London production of the play and promptly came to be called "a Trilby hat". The trilby is a narrow-brimmed type of hat that was once viewed as the rich man's favored hat, particularly in Britain, and was frequently seen at horse races. Traditionally made from rabbit hair felt, it is now usually crafted from materials like tweed, straw, and wool blends. The hat reached its peak of popularity in the late 1950s and early 1960s and later experienced resurgences in the 1980s and early 2010s. It has been associated with iconic figures such as Frank Sinatra and fictional characters like Inspector Gadget.
