CF tan long sleeve shirt The Distinctive Environmental Uniform (DEU) was adopted as a dress and duty uniform by the Canadian Forces in the mid-1980s, marking a return to distinctive service uniforms. Soldiers, sailors and airmen of the CF were identified as belonging to an "environment" or "element", either Sea, Land or Air. Members of the land element had the former CF Uniform replaced with a tan DEU for summer and CF Green DEU for winter. The jackets and trousers were similar to the CF Uniform with the exception of the addition of shoulder straps. The jackets were also cut differently, lacking shoulder padding, and of different material. Uniforms for the sea element returned to black and white in line with naval traditions, and the air element returned to the postman blue previously worn by the Royal Canadian Air Force before Unification. In the autumn of 1986, 50 percent of the CF had received winter uniforms (some 54,000), with the remainder issued in the autumn of 1987. Issue of the "tans" began in the spring of 1987, with the final 50% of the issue made in the spring of 1988. In the 1990s, specifically female clothing began to be phased out; while the skirt would remain an optional item of dress in the 21st Century, the "dickie" and female Service Dress Cap were abandoned. The issue of "male" jackets also became common in lieu of a female jacket lacking external breast pockets and buttoning on the other side. In the late 1990s, the tan DEU was deleted, and Combat Dress was made the standard dress of the day. A free issue of three short-sleeved green shirts was made in 1998, with 47,000 new pattern short-sleeved shirts produced by mid-March of that year and 10,000 new shirts a week coming off production lines. The green DEU jacket, trousers and skirts were changed from the heavyweight winter material to a newer all-season fabric that was slightly lighter. Long sleeved shirt issue was reduced from four per member to two as the DEU was reserved for ceremonial purposes rather than office work.
