If the dress code is black tie, does the bow tie have to be black? I have a black as well as burgundy, also a black+white cravat, and have always worn either depending on my mood at the time of dressing (I used to attend a lot of functions, not that many nowadays), but the increase in questions on black-tie have got me thinking now. Or is the cravat strictly off-limits (too informal) for a dinner function? How about a cummerband? My favourite is to wear the DB (I'm not so fond of the way I look in my SB), would it end up looking too busy for a DB w/cummerband? Enquiring minds want to know!
