A formal dance is a structured social event where attendees dress in elegant attire, often including formal dresses for women and suits or tuxedos for men. These events typically feature a specific theme or occasion, such as proms, weddings, or galas, and often include a program of organized dances, such as the waltz or foxtrot. At formal dances, guests usually follow a set of etiquette rules, including proper introductions and respectful behavior on the dance floor. Music is a key element, often provided by a live band or a DJ, creating an atmosphere for socializing and dancing.
