Contrary to many people's expectation, not a dress that is worn in the morning.
It is a very formal attire, originally designed for daytime wear during a wedding. However, it now is acceptable protocol for evening weddings as well. The morning coat attire gives men a turn-of-the-century appearance. It is comprised of either a black or gray coat with matching gray and black striped pants, a pearl gray or light gray vest, gray and black striped four-in-hand tie (standard necktie) or ascot tie, and either a collared or wing collar shirt. The coat is designed as either a "Cutaway" with tails or a "Stroller" without tails.
