The term 'Belles of Balls' refers to debutantes, or young women who are formally presented to society at a formal ball. The term is derived from the French word 'DEBUTANTE, ' which means 'female beginner.' Debs, as they are often called, are typically young women between the ages of 16 and 21 who have been invited to attend a formal ball, usually hosted by their parents. At the ball, the debs are formally presented to society and are expected to make a good impression.
