The two key features of a Fedora are a soft brim and a pinched crown. Apart from that, the crown height is 4.5 inches, and the dents on the crown vary for different kinds of Fedoras. Some of the popular crown designs are teardrop crown, center dented crown or the diamond crown. Further, even though the brim is soft, it is significantly wide, approximately 2.5 inches.
Fedoras can be made from wool or wool alternatives such as cashmere or felt, but they can also be made from summer fabrics such as cotton, linen, or hemp. Most times, the crown is structured, but there is a rollable and crushable Fedora variety too. Also, Fedoras are mostly plain without much decoration, but there can be a grosgrain ribbon around the crown.
