A shift dress is a simple, short, above-the-knee dress. The bust is fitted with darts, and the skirt is either cut straight or with a narrow A-line. The dress doesn’t provide any definition to the waist, and the neckline is usually a fairly high scoop neck or boatneck. A shift dress is typically sleeveless, although short-sleeve and long-sleeve versions are also popular. A shift dress can be created in a variety of styles.
