Formal wearFormal wear or full dress is the Western dress code category applicable for the most formal occasions, such as weddings, christenings, confirmations, funerals, Easter and Christmas traditions, in addition to certain state dinners, audiences, balls, and horse racing events. Formal wear is traditionally divided into formal day and evening wear, implying morning dress (morning coat) before 6 p.m., and white tie (dress coat) after 6 p.m.
Morning dressMorning dress, also known as formal day dress, is the formal Western dress code for day attire, consisting chiefly of, for men, a morning coat, waistcoat, and formal trousers, and an appropriate gown for women. Men may also wear a popular variant where all parts (morning coat, waistcoat and trousers) are the same colour and material, often grey and usually called "morning suit" or "morning grey" to distinguish it; considered properly appropriate only to festive functions such as summer weddings and horse races, which consequently makes it slightly less formal.
Black tieBlack tie is a semi-formal Western dress code for evening events, originating in British and American conventions for attire in the 19th century. In British English, the dress code is often referred to synecdochically by its principal element for men, the dinner suit or dinner jacket. In American English, the equivalent term tuxedo (or tux) is common. The dinner suit is a black, midnight blue or white two- or three-piece suit, distinguished by satin or grosgrain jacket lapels and similar stripes along the outseam of the trousers.
SuitA suit, lounge suit, or business suit is a set of clothes comprising a suit jacket and trousers of identical textiles worn with a collared dress shirt, necktie, and dress shoes. A skirt suit is similar, but with a matching skirt instead of trousers. It is considered informal wear in Western dress codes. The lounge suit originated in 19th-century Britain as a more casual alternative for sportswear and British country clothing, with roots in early modern Western Europe.
