Top hat

A top hat, beaver hat, high hat, silk hat, cylinder hat, chimney pot hat or stove pipe hat, sometimes also known by the nickname "topper", is a tall, flat-crowned, broad-brimmed hat, predominantly worn by men from the latter part of the 18th to the middle of the 20th century. By the end of World War II, it had become a rarity in ordinary dress, though it continued to be worn in specific instances, such as state funerals, also by those occupying prominent positions in the Bank of England and by certain City stock exchange officials.
