off-shoulder leotard
A leotard that is naturally designed with a low and wide-cut neckline, not covering the shoulders or upper chest area, leaving them bare.
Off-shoulder leotards are meant to emphasize and accentuate the wearer's shoulders, collarbone, and neck (or nape), with the sleeves of an off-shoulder leotard sitting on the upper arms instead of on top of the shoulders.
For the leotard to qualify for this tag, the sleeves must be attached to the leotard. If they are not, then it is a strapless leotard with detached sleeves.
Off-shoulder leotards and strapless leotards are mutually exclusive to each other.
