A female attendant in a traditional quinceañera court is called a dama.
The plural form is damas, and these attendants traditionally accompany the quinceañera as part of her court of honor. They may participate in the entrance, formal photographs, presentations, and a choreographed waltz with the celebrant and the chambelanes.
The court is one of the event’s ceremonial features, but it is not required. Some families select a large court, while others choose only a few close friends or relatives. Modern celebrations may also alter the traditional gender arrangement or use a group of attendants without emphasizing Spanish titles.
Dama is easy to mix up with madrina. A dama is an attendant, whereas a madrina is generally a female sponsor or godmother. The central celebrant herself is the quinceañera, so that word does not describe a court member.
