Black Velour Derby

Derby hats, also known as bowler hats, are a distinctive style of hat with a rounded crown and a short brim. While "derby" and "bowler" are the most common names for this type of hat, there are a few other regional or colloquial names you might come across:

Coke Hat: In some regions, particularly in parts of the United States, the bowler hat is called a "coke hat" because it was historically associated with the Coca-Cola Company.

Bombín: In Spanish-speaking countries, the bowler hat is often referred to as a "bombín."

Billycock: In parts of the United Kingdom, especially in Lancashire and Manchester, the bowler hat is sometimes called a "billycock" or "billycock hat."

Bob Hat: This is a slang term for a bowler hat that was used in some regions.

Derby Bowler: A combination of the two most common names for this hat, the "derby bowler" is a hybrid term.

These terms are not as widely used as "derby" or "bowler," but they might be encountered in specific regions or historical contexts.
