What collective English name is commonly given to the attendants in a quinceañera court?

The attendants in a quinceañera court are commonly called the court of honor.

The court of honor is the group that accompanies the honoree during formal parts of the celebration. Members may enter with her, pose for official photographs, and perform a rehearsed dance or waltz.

Traditionally, the court may contain fourteen people, often divided into young women and young men. Spanish-language descriptions may use terms such as damas and chambelanes for particular members, but “court of honor” describes the group collectively in English.

The title is ceremonial and does not imply a legal or official position. Many modern quinceañeras modify the court’s size, composition, clothing, or role to reflect the honoree’s preferences.
