What Spanish name is commonly given to the formal attendant group at a quinceañera?

The formal attendant group at a quinceañera is commonly called the corte de honor.

Corte de honor translates literally as “court of honor.” It refers to the group selected to accompany the quinceañera during important public parts of the celebration. The court may include damas, or female attendants, and chambelanes, or male attendants, depending on the family’s preferred format.

Members of the corte de honor often participate in a coordinated entrance, formal dances, posed photographs, and other planned elements of the reception. Their clothing may be coordinated with the celebrant’s outfit, although there is no single worldwide dress code.

The phrase describes a ceremonial group, not a religious office. Quinceañera customs differ across countries and families, so some modern celebrations use a reduced court or replace it with close friends and relatives without a formal title.
