Cotillion is a formal social dance event, often associated with the debut of young people into society. Traditionally, it involves a series of dances and etiquette lessons, helping participants learn proper social behavior and dance skills. The event is typically held for teenagers, particularly in the Southern United States, and is often organized by local community groups or private clubs. During a cotillion, participants usually wear formal attire, such as evening gowns for girls and tuxedos for boys. The event often includes a variety of dances, such as the waltz and foxtrot, and may also feature a presentation ceremony where participants are introduced to the community.
