This is such a southern tradition. It's call a Debutant Ball Presentation. It's when a young lady is being presented into society by her parents. Each girl had her father and a date as escorts. First the are presented, bow in front of everyone, all girls are announced, then the dance with their dad and then dates. The goal of the bow is to go the lowest with out falling. There is a lot of choreography and practicing that goes into these event. The presentations are put together by different groups and held at country clubs. Here is the Houston Country Club Deb Ball that was held the day before Thanksgiving. Man was it a party. I think 1200 guests attended this one.
