A dress (also known as a frock or a gown) is a garment traditionally worn by women or girls consisting of a skirt with an attached bodice (or a matching bodice giving the effect of a one-piece garment). It consists of a top piece that covers the torso and hangs down over the legs. A dress can be any one-piece garment containing a skirt of any length, and can be formal or casual. A dress can have sleeves, straps, or be held up with elastic around the chest, leaving the shoulders bare. Dresses also vary in color. The hemlines of dresses vary depending on modesty, weather, fashion or the personal taste of the wearer. Dresses are outer garments made up of a bodice and a skirt and can be made in one or more pieces. Dresses are generally suitable for both formal wear and casual wear in the West for women and girls. Historically, dresses could also include other items of clothing such as corsets, kirtles, partlets, petticoats, smocks, and stomachers.
