Fedora hat
Extracted from the Wikipedia article Fedora.
The fedora hat's brim is usually around 2.5 inches (6.4 cm) wide, but can be wider, can be left raw-edged (left as cut), finished with a sewn overwelt or underwelt, or bound with a trim-ribbon. Stitched edge means that there are one or more rows of stitching radiating inward toward the crown. The Cavanagh edge is a welted edge with invisible stitching to hold it in place and is a very expensive treatment that requires a highly-skilled craftsman. Fedora hats are not to be confused with small brimmed hats called trilbies.
