A
Norfolk jacket is a loose, belted,
single-breasted jacket with
box pleats on the back (and sometimes front), now 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 for the
Duke of Norfolk or for 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.
