In quinceañera traditions, what term commonly describes the male attendants?

In quinceañera traditions, the male attendants are commonly called chambelanes.

A chambelán is traditionally a young man who forms part of the celebrant’s court or accompanying group. The plural chambelanes is used when referring to several male attendants. Depending on the family and country, these attendants may be relatives, friends, or classmates.

Chambelanes often participate in a choreographed entrance or formal dance with the quinceañera and other members of the court. Their clothing may be coordinated with the celebrant’s gown, although styles range from formal suits to regionally influenced outfits.

The term is not universal. Some families use English phrases such as escorts or court members, and arrangements differ greatly between celebrations. Chambelanes should also not be confused with mariachis, who are musicians, or padrinos, who are sponsors or honored adults connected with the event.
