Khaki Service Dress was introduced into Canadian service in 1903. Officers purchased most of their uniforms and equipment from tailors, but some items were acquired through the military supply system on repayment. The standard uniform for officers during the First World War was Service Dress. This consisted of a tunic, worn with a Sam Browne belt, and breeches. Officers wore a collar and tie, separating them from the Other Ranks who wore closed collars. Shirts were generally of a cream or light green colour, with separate collars secured by collar buttons. A silk or knitted necktie was usually secured to the collar with a collar pin. Metal insignia, ie: cap badges, collar badges and rank insignia were to be bronze. In Canada, metal rank insignia was worn on the epaulettes, but upon arrival overseas, worsted rank insignia was worn on the cuffs.
