A quinceañera may traditionally receive or give away a last doll as a symbolic childhood object.
The last doll represents the celebrant's movement away from childhood. In some versions of the ceremony, a parent presents the doll to the quinceañera; in others, she gives it to a younger sibling or another child. The action expresses continuity between generations while marking a new stage in the celebrant's life.
The custom is often called the doll ceremony or the last doll ceremony. It is not performed at every quinceañera, and its form differs across families and communities. Some celebrations use a porcelain doll, while others use a specially dressed doll chosen to match the event.
The last doll is one of several symbolic traditions associated with quinceañeras. Shoe changes, tiaras, bouquets, candles, and formal dances may also appear, but none is compulsory everywhere. Treating one version as universal can obscure the celebration's regional diversity.
