1940s or White Tie Attire ENCOURAGED
White tie, (also called full dress, evening dress, full evening dress), is the most formal evening dress code in Western fashion. For men, it consists of a black tailcoat worn over a white starched shirt, marcella waistcoat and the eponymous white bow tie worn around a detachable collar. High-waist black trousers and patent leather shoes complete the outfit, although decorations can be worn and a top hat and white scarf are acceptable as accessories. Women wear full-length evening dresses and, optionally, jewelry, tiaras, a small bag and evening gloves.
The dress code's origins can be traced to the end of the 18th century, when high society men began abandoning their breeches, lacy shirts and richly decorated evening coats for more austere tailcoats in dark colors, a look inspired by the country gentleman. Fashionable dandies like Beau Brummell popularized a minimalistic style in the Regency era, tending to favor dark blue or black tailcoats, often with trousers instead of breeches, and white shirts, waistcoats and cravats. By the 1840s the minimalistic black and white combination had become the standard eveningwear for upper class men.
