Fedora is one of the most well-known hat styles. A fedora hat has small soft brim, generally 1.5" - 2.25" wide (stingy brim, wide brim fedora). The brim can be curled up all around, or just in the back with the front turned down. Fedora hat has a pinched crown with a dented, C-crown or diamond crown top. Most often accented with a simple ribbon band with a small side bow, a pin or feather.
A trilby is a narrow, stringy brim fedora hat. Originally designed for a women's role, Princess Fedora Romazov, played by Sarah Bernhardt in the French play Fédora in 1882. Though, her hat was a soft wool felt hat, it did not resemble what we know today as a fedora. It seems that a savvy New York hatter, Knox began to advertise his wool felt hat style made for men as a hat designed for American men to be worn for any and all occasions, and called it a fedora, referencing the theatrical sensation and the lavish, elegant French fashion.
