Does a man have to wear a vest or cummerbund with a tux?
On One Hand: They Are TraditionalVests and cummerbunds are common accessories of the tuxedo. A simple vest or cummerbund may be standard dress code at your event, so you should bring one or the other. For less formal occasions, a colorful or patterned vest or cummerbund allows for more self-expression. (Note: If you take this route, choose a simple black bow tie to avoid clashing colors or patterns.)On the Other: There Are ExceptionsA man does not always have to wear a vest or cummerbund with a tux. In fact, there are times when they are inappropriate. For example, if you are wearing a double-breasted coat, you should not wear a cummerbund because it will not fit correctly. Also, you should not be the only guest wearing a vest. A tuxedo need not have either to be complete because the jacket is what really makes the tuxedo a tuxedo.Bottom LineConsult with male friends or family attending the event. If you cannot get an absolute answer as to whether others are wearing a vest or cummerbun
