The purpose of a bed skirt is to give a stylish appearance to a bed without exposing the sides of the box spring or any space under the bed that may be used for storage.
While many people tend to consider a dust ruffle and a bed skirt to be the same type of bedding accessory, that is not the case. While both serve the purpose of covering the space between the edge of the comforter or bedspread and the floor, they are actually constructed differently and are positioned on the bed using different means.
