Receiving an invitation to a wedding that specifies a "black tie" dress code can be rather intimidating because your standby LBD won't cut it for this type of event. Although, "black tie" requires women to wear formal gowns, don't let the name fool you -- you don't have to show up in head-to-toe black. If you decide to wear a color or a print, just make sure it won't clash or match the bridesmaids' dresses or steal attention away from the bride. Black tie attire doesn't have to be mega-expensive, either. All of our gown choices cost less than $200.
