Uniform regulations for officers were first issued by Lord Anson in 1748, and remained unchanged for nearly twenty years. Reportedly, the officers themselves advocated its adoption, as they "wished to be recognised as being in the service of the Crown." The "best uniform", consisting of an embroidered blue coat with white facings, worn unbuttoned with white breeches and stockings, was worn for ceremonial occasions; the "working rig" was a simpler, less embroidered uniform for day-to-day use. In 1767 the best uniform was abolished and replaced by the working rig, with a simpler "undress" uniform for day-to-day use. By 1795, as a result of the French Revolutionary Wars, a plain blue "undress" coat had been introduced for everyday use, and epaulettes were officially introduced. By 1846, all officers wore epaulettes. The white facings came and went over the years, briefly becoming scarlet (1830-1843). Though stripes of lace on the cuffs had been used to distinguish the different ranks of admiral since 1795, the first version of current rank insignia, consisting of stripes with a "curl" in the top one, was introduced for all officers in 1856.
