Black tie

Black tie is a formal evening dress code centered on the dinner jacket, traditionally paired with a bow tie, and corresponding formal eveningwear.

Dinner jacket: A formal evening jacket, usually black or midnight blue, worn as the defining garment of black tie. It is the central menswear garment that gives black tie its familiar silhouette.
Black tie optional: An event dress code that welcomes black tie but permits a dark suit as an alternative. It relaxes black tie’s strict expectation of eveningwear while preserving its formal tone.
Prince Edward, Duke of Windsor: The British prince who popularized influential innovations in men’s fashion during the early twentieth century. His sartorial influence helped make alternative dinner-jacket styles socially prominent.
Lounge suit: A matching jacket and trousers worn as a standard daytime or business suit. It is less formal than black tie and lacks the dinner jacket’s eveningwear details.
Black tie (necktie): A black bow tie traditionally worn with a dinner jacket at formal evening events. The dress code takes its name from this defining accessory.
Creative black tie: A flexible black-tie interpretation that permits distinctive colors, textures, and accessories. It shows how hosts can preserve the formal framework while allowing personal variation.
Henry Poole & Co.: A London tailoring house founded in 1806 and associated with the development of the dinner jacket. The firm is linked to the dinner jacket’s early history at its Savile Row origins.
Morning dress: A formal daytime dress code featuring a morning coat, waistcoat, and striped trousers. Its daytime purpose and coat distinguish it from black tie’s evening setting.
Evening gown: A formal full-length dress designed for evening occasions. It is a traditional counterpart to the dinner jacket in women’s black-tie attire.
Dress code: A set of rules or expectations governing clothing for a particular setting or event. Black tie is one named system within the broader practice of event dress codes.
