In fashion, a ballerina neckline refers to the classic necklines styles on the dance attire, or leotards, worn by the dancers. Popularized especially by designers and fashion icons of the mid-twentieth century, the term ballerina (or ballet) neckline can be construed in a variety of ways. Some classically styled or traditional leotards have a low, wide, vertically scooped neckline and others are cut in a high horizontal oval shape. Both styles may be accompanied by a very low scooped back opening.
