What is the usual name for the group of attendants who participate in a quinceañera?

The usual name for the group of attendants who participate in a quinceañera is the court of honor.

Members of the court often accompany the quinceañera during formal portions of the celebration, including the entrance and the choreographed waltz. They may be friends, siblings, cousins, or other relatives chosen by the honoree and her family.

A court can include young women called damas and young men called chambelanes, although terminology and group composition vary. Some modern celebrations use a mixed group, a smaller group, or no court at all.

The court of honor is sometimes compared with a bridal party because of coordinated clothing and ceremonial roles, but a quinceañera is not a wedding. Its purpose is to support and present the birthday honoree.
