A dress is a one-piece garment that consists of a top piece and an attached skirt. The oldest dress is believed to have been worn in ancient Egypt. Over the years, the style of dresses has evolved with changing fashion trends. Today there are different styles of dresses—from formal ball gowns to casual sundresses. Dresses come in all shapes and sizes, with some falling mid-calf, mid-thigh, or to the floor. Dresses can be worn on a casual day at home or a glamorous night out. Understanding different dress looks can help you choose an outfit fit for any occasion.
