The Canadian Army Service Corps wore the same uniforms as the rest of the Canadian Expeditionary Force. They had started off the war in Canada wearing the 1903 pattern service dress tunic which had been worn in the pre war era. The principle characteristics of this uniform were 7 buttons in the front and a stand up collar which was fastened by two hooks. These continued to be worn overseas as a means of distinguishing themselves from their British counterparts until supplies ran out.
As a special distinction, soldiers who were part of the First Canadian Contingent were allowed to wear coloured shoulder straps.For members of the CASC, that meant a white shoulder strap with 2 blue stripes down the middle.
