Norfolk jacket

A Norfolk jacket is a loose, belted, single-breasted jacket with box pleats on the back and front, with a belt or half-belt. The style was long popular for boys' jackets and suits, and is still used in some (primarily military and police) uniforms. It was originally designed as a shooting coat that did not bind when the elbow was raised to fire. It was named either after the Duke of Norfolk or after the county of Norfolk and was made fashionable after the 1860s in the sporting circle of the Prince of Wales, later Edward VII, whose country residence was Sandringham House in Norfolk.
