I'm trying to learn about a new type of hat called the “bowler” hat. Can you tell me more about it?

The bowler is a classic men's hat with a curved brim that covers the forehead and back of the head. It has been popular since the 19th century, especially in the UK. In the US, it was worn by gangsters and other criminals during the Prohibition era, but today it is mainly worn as a casual accessory.
