There is a lot of preparation before a quinceanera celebration. The most important and expensive preparation is buying the girl’s dress. The dress is like a wedding dress but is usually pink; however, today many girls also wear dresses in other light colors. The birthday girl chooses 14 girls and 14 boys who will be her attendants at the ceremony and the dinner dance that follows. Traditionally, these girls and boys are younger than the birthday girl, but sometimes they are the same age.
