What is the formal group accompanying a quinceañera commonly called?

The formal group accompanying a quinceañera is commonly called the court of honor.

A court of honor typically consists of friends or relatives selected by the celebrant. Depending on regional and family custom, it may include damas, young women, and chambelanes, young men who participate in the entrance, formal dances, and photographs.

The court’s role helps give the reception a ceremonial structure. Members may wear coordinated formal clothing and perform a choreographed waltz or other dance with the quinceañera. Some celebrations use only a few attendants, while others have a larger group.

The court of honor is not the same as a wedding party, even though the visual arrangement can look similar. A quinceañera may have no court at all, and the terminology or composition can change across countries and communities.
