Dama is the Spanish word for “lady” used for a female member of a traditional quinceañera court.
The plural form is damas. These attendants may accompany the celebrant during the entrance, formal dances, photographs, and other ceremonial moments. In a traditional court, they are paired with male attendants called chambelanes.
The word is not a title meaning the celebrant herself. The quinceañera is the person whose fifteenth-birthday celebration is being held, while a dama is one of the supporting court members. Adult sponsors are generally called madrinas or padrinos, depending on gender.
Families adapt the court to their own circumstances. A celebration may include relatives, friends, or no formal attendants, so the presence and number of damas are customary rather than mandatory.
