Q:I know that the answer to the question "What did the débutantes do during the event?" is in "Court presentations of aristocratic young ladies to the monarch took place at the palace from the reign of Edward VII. These young women were known as débutantes, and the occasion—termed their "coming out"—represented their first entrée into society. Débutantes wore full court dress, with three tall ostrich feathers in their hair. They entered, curtsied, and performed a choreographed backwards walk and a further curtsy, while manoeuvring a dress train of prescribed length. (The ceremony, known as an evening court, corresponded to the "court drawing rooms" of Victoria's reign.) After World War II, the ceremony was replaced by less formal afternoon receptions, usually without choreographed curtsies and court dress.". Can you tell me what it is?
