Which version of Fedora Core are you using

The fedora is a soft felt hat that is creased lengthwise down the crown and pinched in the front on both sides. It was invented in the mid-1910s. Any hat that resembles the soft felt version is also usually called a fedora, including straw and twill ones. Similar hats with a C-crown (with an indentation for the head in the top of the crown) are occasionally called fedoras. It is usually worn by men, but ladies' versions can also be found.

The popularity of the fedora has resulted in being able to purchase one in nearly any style. Fedoras can be found in nearly any color imaginable, but black, grey, and tan/brown are the most popular and universal.

In traditional courtesy, when a man doffs this hat (women did not tip their hats), he would often grasp a fedora by placing his thumb in one of the pinched indentations at top front and at least two fingers on the other side.

In Europe a fedora is also called a trilby. They typically have a shorter, "stingy" brim and the back of the brim is distinctively more sharply upturned as a result.

The word comes from the title of a 1882 play by Victorien Sardou, Fédora, the heroine of which wore this style of hat.
