A court with 14 damas and 14 chambelanes has 28 attendants.
Traditional descriptions of a quinceañera court often give 14 girls, called damas, and 14 boys, called chambelanes. Together, these attendants form a balanced group accompanying the honoree during formal entrances, dances, or presentations.
The number 14 can be understood symbolically: with the quinceañera herself, the group can total 15 young people. This arrangement is a tradition rather than a universal rule.
Many modern celebrations use smaller courts, mixed-gender groups, relatives of different ages, or no court at all. Therefore, 28 is the count for the specified traditional arrangement, not a required number for every quinceañera.
