Since the mid-eighteenth century, when naval uniforms were introduced, Flag Officers had different full-dress and undress versions, the latter being worn from day to day, the former only for formal occasions. By the late nineteenth century, an officer's full dress uniform consisted of a navy double-breasted tailcoat with white facings edged in gold (on the collar and cuff-slashes), gold lace (indicating rank) on the cuffs, epaulettes, sword and sword-belt, worn with gold-laced trousers (except for Sublieutenants and warrant officers) and a cocked hat.This order of uniform lasted through the first half of the twentieth century, being placed 'in abeyance' at the onset of the Second World War, and was worn by Prince Philip at the Coronation of Elizabeth II. In 1960, full dress uniform was reintroduced in the form of Ceremonial Day Dress. Worn only by limited categories of senior officers this is very similar to the old full dress, but without fringed epaulettes or cuff slashes, and worn with a peaked cap.
