Informal attire

Informal attire, also called international business attire, Western business attire, or Tenue de ville is a dress code, typified by a suit and necktie. On the scale of formality, informal attire is more formal than casual but less formal than semi-formal. It is more presentational than semi-casual, but offers more room for personal expression than semi-formal dress.

Informal should not be confused with casual, not even smart casual — in loose common usage, many people refer to informal dress as semi-formal or formal and formal dress (in the technical sense — that is, white tie, black tie, and similar) as very formal. The technical definition of informal is used in this article.

The informal attire is most commonly used for business events and meetings, job interviews, or in professions like law and finance. It's a conservative dress code that aims to show respect to the situation and not draw attention.

Informal attire for men consists of a lounge suit, made up of a jacket with matching trousers. The suit is typically dark-coloured (without a pattern or with a subtle one): gray, dark blue, brown, or black. The suit is worn with a long-sleeved shirt, usually in white or light blue color, leather dress shoes in black or brown color and a conservative necktie.

Informal attire is today considered a form of dress customarily appropriate for all formal settings, which do not explicitly require white tie or black tie. For instance, it is commonly worn to religious services and funerals, in government offices and schools. Some professions, like law or finance, may require it. At present, informal attire is the typical dress at daytime weddings in the United States and during the main rituals of Hindu weddings, serving as a replacement for the increasingly rare morning dress.
