The white mess uniform consists of a white mess jacket cut on the same design as the blue mess jacket but with the sleeve trimmings of white braid; white waistcoat; white trousers; white shirt, collar and cuffs; the white cap; and white shoes.
The overcoat for officers is a double-breasted ulster of olive-drab cloth extending to about ten inches below the knee (overcoats reaching to the knee only are authorized for field service), with pleated back and a wide rolling collar, buttoning to the neck, with two rows of large flat horn buttons of the same color as the coat, five in each row, having a pocket with vertical opening on each side at the waist. The rank of the wearer is indicated by the trimmings on the sleeves. The overcoat for General officers has a band of black mohair braid one and one-quarter inches wide around the sleeve two and one-half inches above the end and another band of black mohair braid one-half of an inch wide placed one and one-half inches above the lower band. The overcoats for officers below the rank of Brigadier General have the ornamentations indicating rank as shown by the accompanying illustrations. For officers of the General Staff Corps the bands of black braid below the sleeve knot are seven-eighths of an inch wide.
