the wife and I will be attending a "black tie optional" fundraiser in a couple of months and wanted some input from those of you that have experience with these types of events. since I don't own a tux I will obviously be wearing a suit, however, i'm not certain which color suit is the most appropriate. navy? charcoal? black? I don't want to seem overdressed so I won't be wearing any loud ties, although, I don't know what's considered loud for ties these days or what might be considered overdressed. do I go with a solid tie? striped? paisley? got any advice?
