What is the Spanish name for the special dress traditionally worn by a quinceañera?

The Spanish name for the special dress traditionally worn by a quinceañera is vestido de quinceañera.

The phrase literally identifies the garment as the quinceañera’s dress. It is often a formal gown, frequently with a full skirt, fitted bodice, decorative fabric, and coordinated accessories. Color, cut, fabric, and ornamentation vary widely according to personal taste and local fashion.

The dress helps make the celebrant visually distinct during the reception, photographs, entrance, and ceremonial moments. Traditional designs may resemble formal ball gowns, but contemporary quinceañeras also use shorter dresses, sleek silhouettes, jumpsuits, or culturally specific clothing.

The vestido de quinceañera is sometimes incorrectly called a wedding dress. Although both can be formal and white dresses may be chosen, a quinceañera dress belongs to a fifteenth-birthday celebration, not a marriage. The dress is only one element of the event; the religious, family, musical, and community aspects can be equally important.
