formal, festive, elegant
Black tie weddings can be tricky. While the men will elevate their looks to tuxedos, women can often get away with anything from formal cocktail dresses to ballgowns, depending on the crowd and the venue. In most cases, black tie events call for a floor length gown but do your best to gauge the event, finding out what the hostess (typically the mother of the bride) and other guests plan to wear. If you're adamantly opposed to wearing a floor-length gown, go with a formal cocktail dress or a high-low option.
