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