Cummerbund

A cummerbund is a broad waist sash, usually pleated, which is often worn with single-breasted dinner jackets (or tuxedos). The cummerbund was adopted by British military officers in colonial India, where they saw it worn by sepoys (Indian soldiers) of the British Indian Army. It was adopted as an alternative to the waistcoat, and later spread to civilian use. The modern use of the cummerbund to Europeans and North Americans is as a component of the traditional black tie Western dress code.
