What is a "tuxedo"?

A tuxedo, also known as a dinner jacket, is a formal suit worn by men for black-tie events and formal occasions. It typically includes a black, midnight blue or white jacket with silk or satin peak or shawl lapels, usually with a single button, or sometimes two or three, black trousers, a white dress shirt with a pleated or pique bib front, a black bow tie, and black dress shoes. The ensemble may also include a cummerbund or waistcoat, typically in black, white or a coordinating color. Tuxedos are traditionally made of wool or a wool blend, and may also be made of velvet or silk for special occasions. The tuxedo is a classic and sophisticated wardrobe item, popular for formal events and occasions.
