Mess dress uniform is the semi-formal type of uniforms used by military personnel, police personnel, firefighters and other public uniformed services members for certain ceremonies, receptions, and celebrations, in messes or on private occasions. It frequently consists of a mess jacket, trousers, white dress shirt, often with standing collar and bow tie, along with orders and medals insignia. Design may depend on regiment or service branch, e.g. army, navy, air force, marines, etc. In Western dress codes, mess dress uniform is a permitted supplementary alternative equivalent to the civilian black tie for evening wear or black lounge suit for day wear - sometimes collectively called half dress - although military uniforms are the same for day and evening wear. As such, mess dress uniform is considered less formal than full dress uniform, but more formal than service dress uniform.
