Lavish, traditional coming-of-age celebration or a young woman’s fifteenth birthday, practiced in Hispanic countries and Latino diaspora communities. Quinceaños parties in upper-class families are similar to debutante balls. They take place in private clubs or fancy hotels, and groups of wealthy women dressed in elegant designer gowns are formally presented to society. Middle-class celebrations are usually less ostentatious and often take place in family homes. The inclusion of a Catholic Mass as part of the festivities is losing popularity. For some assimilated families it has been replaced by a sweet-sixteen party.
