A formal tuxedo requires only a few additional accessories, but these must be chosen carefully. A cummerbund and a bow tie masterfully complete a formal look, underlining the elegant effect of the tuxedo. The classic colours for a cummerbund are black or red. The ostentatious man may also occasionally select different colours or patterns, depending upon the strictness of the dress code. The specified style rules should always be adhered to at semi-formal or formal events, so choose a black cummerbund for such occasions. Always select a bow tie matching the cummerbund in order to achieve a harmonious overall appearance.
