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.
DressA dress (also known as a frock or a gown) is a garment traditionally worn by women or girls consisting of a skirt with an attached bodice (or a matching bodice giving the effect of a one-piece garment). It consists of a top piece that covers the torso and hangs down over the legs. A dress can be any one-piece garment containing a skirt of any length, and can be formal or casual. A dress can have sleeves, straps, or be held up with elastic around the chest, leaving the shoulders bare. Dresses also vary in color.
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.
Informal wearInformal wear or undress, also called business wear, corporate/office wear, tenue de ville or dress clothes, is a Western dress code for clothing defined by a business suit for men, and cocktail dress or pant suit for women. On the scale of formality, it is considered less formal than semi-formal wear but more formal than casual wear. Informal or undress should not be confused with casual wear such as business casual or smart casual; most situations calling for “informal wear” will usually tolerate casual dress to varying extents.
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.
