A debutante ball, sometimes called a coming-out party, is a formal ball that includes presenting debutantes during the season, usually during the spring or summer. Debutante balls may require prior instruction in social etiquette and appropriate morals. The dress code is white tie and tails for men, and strictly floor-length pure white ball gown for women. Long white gloves are commonly worn by female debutantes and are considered a symbol of upper-class femininity.
