Morning 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. The correct hat would be a formal top hat, or if on less spacious audience settings optionally a collapsible equivalent opera hat. Debrett's states that morning dress should not be specified as the dress code for events starting after 6 p.m. If a formal event will commence at or after 6 p.m., white tie should be specified instead. The semi-formal daytime counterpart of this code is the black lounge suit. Morning dress is generally restricted to certain weddings, royal, governmental or municipal audiences, and social season events, e.g., horse races. It may also be seen sometimes worn at church services, as well as fraternal orders, and gentlemen's clubs. History The name originated from the practice of gentlemen in the nineteenth century riding a horse in the morning with a cutaway front, single breasted morning coat. The modern twentieth century morning dress was originally a more casual form of half dress, but as the nineteenth century progressed it gradually became acceptable to wear it in more formal situations instead of a frock coat. In the Edwardian era it took over in popularity from the frock coat as the standard daytime form of men's full dress. When it was regarded as a more casual coat, it was common to see it made with step collars (notched lapels in American English), but as it took over from the frock coat in formality it began to be made with the more formal pointed lapels (peaked lapels in American English). Composition Morning dress consists of: a morning coat (the morning cut of tailcoat), now always single breasted with link closure (as on some dinner jackets) or one button (or very rarely two) and with pointed lapels, may include silk piping on the edges of the coat and lapels (and cuffs on older models with turnup coat sleeves). a waistcoat, which matches the material of the
