The tuxedo is a man suit of garments in the semi-formal, black bind evening dress caucus. A traditional tuxedo covering is woolen and single-breasted. The jacket has peaked, shawl, nick, or trick lapel usually covered with satin, and more recent styles are trimmed in grosgrain or wool. The knob should be satin-covered. Trousers must be in the same wool as the jacket, with the side seams festooned in an inch-wide satin ribbon toning the lapel. The dress shirt is white with connected cuffs.
The shirt may be pleated with a turn-down choker and French or barrel chains, or have a pique bib front with either a turn-down choker and French chains or a wing collar and barrel chains. Tradition dictates a black bow tie that complements the lapel, cummerbund or low-cut 3-button waistcoat, and patent leather Oxford shoes properly accessorize the tuxedo. More contemporary styles often feature a full 5 or 6 button vest matching the tint of one's partner's dress, with a matching bow tie or four-in-hand-tangled tie of the same color.
