The traditional quinceañera custom of presenting a final childhood doll is called the last doll. In Spanish, it is often known as the última muñeca.
The doll represents childhood and the transition associated with turning 15. In some celebrations, a younger sister or another child receives the doll afterward, while in others the honoree keeps it as a keepsake. The exact presentation varies widely and is not an obligatory part of every quinceañera.
The last-doll custom is one of several symbolic rituals that families may add to the celebration. Other traditions can include a formal presentation, a special dance, a tiara, or gifts from parents and sponsors. Because quinceañera customs differ by country and family, the meaning attached to the doll may be personal as well as traditional.
