The one-shoulder silhouette replaces the off-the-shoulder “Bardot” as the shoulder-show neckline of choice. The one-shoulder look is a bit more sophisticated with its asymmetric cut, and offers myriad options for layering. Designers show the look on its own or worn over tees or tanks, in sleeveless or single-sleeved styles. The diagonal neckline can be slanted toward the opposite underarm, toga-style — or can drape over the top of the shoulder for a modified effect. The detail works for both knits and wovens, whether easy or body-con, and looks particularly fresh for activewear silhouettes.
