Socks and tights are important pieces of a girl's wardrobe. Socks prevent blisters and reduce foot odors, while tights can be layered under a skirt or dress for extra warmth. Girls' socks are available in athletic or trouser versions, and in cuts from ankle to knee-high. They're sized according to shoe size or age group (infant, toddler, child, and youth). Girls' tights are dressy or casual, come in a variety of colors and textures, and are usually sized by age or height and weight.
