The celebration begins with a Thanksgiving Mass, in which the quinceañera arrives in formal dress, accompanied by her parents, godparents, seven maids of honor and seven chamberlains. After the Mass, the younger sisters, female cousins and friends of the quinceañera pass out party favors, and the quinceañera leaves her bouquet in an altar to the Virgin Mary. The Mass is followed by a party at either the quinceañera's home or in a banquet hall rented for the occasion.
