Both white tie and black tie are worn to formal occasions, but the white tie is the more formal event of the two. A strict dress code needs to be followed, with impeccable tailoring and attention to detail. There is little room for freedom of expression or to wear something that reflects your personality. In both dress codes, men can wear tuxedos, but for a white tie, you will wear a white bow tie, white tuxedo shirt and waistcoat, black tailcoat, black tuxedo trousers, and black shoes.
