The fedora’s enduring popularity is due to the wide range of styles available. Even if shades of black, grey and brown are the most common, the fedora is conceivable in all sorts of materials and colours. Headwear with a similar shape as the felt version is also referred to as a fedora. The trilby, which has a similar shape, is derived from the fedora. The main difference is that the brim is narrower, whilst being emphasised and curved up at the back.
