The first RAF mess dress was introduced in 1920 and it featured a high waisted single-breasted blue-grey jacket which tapered to a point at the front below the waist. A blue-grey waistcoat, trousers and black shoes were also worn. Rank was indicated on shoulder boards in gold lace. This uniform was modified in 1928 when the shoes were replaced by boots and overalls with gold lace and bright blue stripes were introduced. This modified form of the uniform lasted until 1934 when it was replaced by a version similar to the current men's mess dress. The wearing of mess dress was suspended during World War II.
