A coat that is naturally designed with a low and wide-cut neckline, not covering the shoulders or upper chest area, leaving them bare. However, this tag is infamous for being frequently misused for open or partially-open coats that are worn hanging off the upper arms, regardless of how they were designed to be worn.
These are regular coats worn hanging off the arms or with shoulder cutouts; they do not count as correct usages of the tag.
If unsure whether or not the clothing in question qualifies as an off-shoulder coat, use the off shoulder tag instead.
