A flower girl is a young female who scatters flower petals down the aisle during a wedding procession. In a traditional wedding procession, flower girls are usually members of the bride or groom 's extended families or a friend of either family and are usually three to ten years old. A flower girl typically walks in front of the bride during the wedding procession and scatters flower petals on the floor before the bride walks down the aisle, but some venues do not allow the scattering of petals. Her outfit usually resembles a smaller version of the bride's wedding dress. Traditionally, a flower girl's clothing was provided by the families of the bride and groom; however, most couples today expect the flower girl's parents to pay for her clothing and other expenses related to her participation.
