Why do queen's guards wear fluffy hats?

Queen's Guards wear fluffy hats, known as bearskins, as part of their ceremonial uniform to symbolize their regimental heritage and tradition. The bearskin hat dates back to the 19th century, originally intended to make soldiers appear taller and more imposing. Additionally, the hats serve to maintain a distinctive and recognizable appearance during state ceremonies and events, reinforcing the British monarchy's image.
