Instructions. 1  Dress Code for a Black-Tie Event Traditionally a black-tie event requires a woman to wear long length dresses like floor length, evening separates or cocktail style because dresses of longer lengths are believed to be more formal than shorter ones.
White-tie is the most formal look for men; it includes a formal tailcoat, a white vest, and a white tie. Black-tie is slightly less formal; men can simply wear a tuxedo, and should take the black tie part literally, wearing an actual black tie (and vest or cummerbund).
