single-shoulder sweater
A sweater with an asymmetrical, diagonal-shaped neckline, leaving a portion of the upper chest area and at least one shoulder bare. These sweaters are typically supported by a single sleeve or a single strap on one shoulder while the other is left bare. The neckline of the sweater starts on top of one shoulder ends underneath the armpit between the torso and opposite arm.
Do not confuse this tag for off-shoulder sweaters that expose one bare shoulder.
