I stopped by a Men's Wharehouse the other day just to see what tux options they have and while talking to the guy I asked him if they do cummerbunds instead of vests. First he looked at me like i had three heads and then said no one really does those anymore nowadays, that cummerbunds are only for formal events. So i said our wedding if pretty formal (we're getting married in a cathedral, and the reception is in a ballroom with a sit down dinner) but it's not black tie required. I really like the look of cummerbunds with bowties better than vests and ties, i think it just looks more polished. But now i'm second guessing myself. The girls are also wearing navy blue tea length dresses. is it ok to have the guys be more formal?
