Full Dress Uniform
Full dress uniform or parade dress uniform is the most formal type of uniforms used by military, police, fire and other public uniformed services for official parades, ceremonies, and receptions, including private ones such as marriages and funerals. Full dress uniforms typically include full-size orders and medals insignia. Design may depend on regiment or service branch, e.g. army, navy, air force, marines, etc.
Although full dress uniforms are often brightly colored and ornamented with gold epaulettes, braids, lanyards, lampasses, etc., most originated as practical uniforms that, with the adoption of even more practical uniforms, were relegated to ceremonial functions.
While full dress uniform is predominantly worn at occasions by commissioned officers and non-commissioned officers, it may also be worn as an optional uniform by some senior enlisted personnel. It is also sometimes worn by members of royal courts, orders of chivalry or certain civilian uniformed services.
