About the top hat

 In the late 18th century, top hats became popular in the West, symbolizing the noble social status of gentlemen. From the mid-19th century to World War II, top hats were the pinnacle of fashion. After the anti mainstream culture in the 1960s, with the abandonment of informal hats for men's daily lives, their usage decreased.

Nowadays, most hover around 5 inches
