“The officers of the Royal Horse Artillery are to wear jackets similar to the private men, with an aiguillette. In parade dress, they are to wear white leather pantaloons, and Hussar boots, with gold binding. On ordinary duties or on march, they are to wear overalls of a colour similar to the private men’s, and a short _surtout_, which is calculated to be worn likewise as a _pelisse_ on service. When attending a drawing-room or levee, they may appear in long coats, with lappels and aiguillettes, the same as are worn with the jacket, but without lace on the seams: or in the Regimental jacket, as they may prefer. The officers of the Horse Artillery are likewise to wear cocked-hats, with the star loop, with their _dress_ regimentals.” [Sidenote: 1823.] By General Order of 5th August, 1823, leather pantaloons and Hessian boots were abolished, blue-grey overalls and Wellington boots being substituted. [Sidenote: 1827.] By General Order of 22nd December, 1827, helmets were abolished, and chacos with tassels substituted. [Sidenote: 1831.] By General Order of 15th March, 1831, drivers’ jackets were assimilated to those of the gunners. [Sidenote: 1831.] By General Order of 20th December, 1831, steel spurs for officers were abolished, and brass spurs substituted. [Sidenote: 1834.] By General Order of 26th May, 1834, cross-belts were abolished, and waist-belts substituted. [Sidenote: 1837.] In 1837 bearskin busbies were substituted for chacos. The plumes were altered in 1839. [Sidenote: 1853.] Sealskin busbies were substituted for bearskin. The officers, however, continued to wear the bearskin until 1855, when the sable busby was adopted. The plume was shortened from 12 to 8 inches. [Sidenote: 1854.] The officers’ _pelisse_ was abolished in this year. [Sidenote: 1855.] The full-dress jacket was altered by reducing the amount of lace. A cross-belt of gold lace with pouch was instituted for the officers; as also a plain blue stable-jacket in place of the undress frock-coat and red embroidered waistcoat. [Sidenote: 1857.] In this year booted leather overalls were instituted; and swan-neck steel spurs for all ranks were substituted for the brass spurs of the officers, and the straight steel spurs of the men. * * * * *
