Everyone needs an adorable little girl to carry flowers down the aisle on their big day. The girls who become the flower girls are usually under 10. This little girl is meant to symbolize childhood and youth. In the case of wedding, a wedding flower girl will walk ahead of the bride. In a wedding, the flower girls usually wear white dresses to accentuate their youth. Actually they may also wear colored sashes or other decorations to coordinate with the rest of the procession.
