The trilby, a type of fedora style hat, is characterized by its short, "stingy" brim. The brim is usually angled down in the front and up in the back, but generally allows you to fashion the brim any way you'd like, with both sides up, or one side up and one down. The trilby in recent years has essentially become synonymous with a regular "fedora" and most people refer to them as the same thing, despite the slight differences. In the early 2000's, the trilby rose to popularity in pop culture due to musicians like Justin Timberlake adopting it as part of his signature style.
