Whether your little girl loves glitz or has simpler taste, dresses are sure to be an important part of her wardrobe. There are many types of girls' dresses, including formal gowns, pageant dresses, lightweight summer dresses, and holiday designs. Sizes typically correspond with age by year, from 4 to 14. However, there may be variations between designers, so it's always a good idea to know your child's measurements. Your daughter can make any dress her own by adding fun accessories.
