Red coat, also referred to as redcoat or scarlet tunic, is a military garment formerly much used by British infantrymen, so customarily that the term became a common synecdoche for the soldiers themselves.

Full dress uniform, also known as a ceremonial 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. Styles tend to originate from 19th century uniforms, although the 20th century saw the adoption of mess dress-styled full-dress uniforms. Designs may depend on regiment or service branch. In Western dress codes, full dress uniform is a permitted supplementary alternative equivalent to the civilian white tie for evening wear or morning dress for day wear – sometimes collectively called full dress – although military uniforms are the same for day and evening wear. As such, full dress uniform is the most formal uniform, followed by the mess dress uniform.
