Tuxedo Suits - A tuxedo or dinner suit is a semi- formal three or two piece suit for evening wear distinguished primarily by satin or grosgrain jacket's lapels, and similar stripes along the out seam of the trousers. Classic tuxedo accessories include a cummerbund, waistcoat, suspenders and a self-tied bow tie. Tuxedos are worn with white shirts that have either a wing collar or a turn down collar. Black patent shoes are usually worn with tuxedos. Tuxedos are reserved for evening events only, and for formal occasions like black-tie weddings, charity galas and nights at the opera.
