Beefeater. Such a strange name for such an important position. The Beefeater outfit features an embroidered red gabardine jacket with a crown insignia and a large, white, ruffled collar. Matching knickers and a belt complete the costume. When you're officially called the Yeomen Warders of Her Majesty's Royal Palace and Fortress the Tower of London, and Members of the Sovereign's Body Guard of the Yeoman of the Guard Extraordinary, perhaps any nickname is an improvement. Ceremonial guards, tour guides and living examples of history, the Beefeaters perform a number of functions for the British Royal Family. This Halloween, take on a bit of royal shine in the Men's Regency Collection Beefeater Costume. This fun and authentic Halloween costume will make you a popular novelty anywhere you go. Add shoes and hose, and consider buying a Beefeater hat, to fully portray the classic Beefeater look.
