off-shoulder bikini
A specific type of shoulder-less bikini designed with a wide low-cut neckline (much like regular off shoulder garments), leaving the shoulders and upper chest area bare. Usually, it is a bikini with sleeves that sit on the arms instead of the shoulders.

Regular bikinis that have their strap slipped off (ie. post #4709241, post #4662556, etc.) do not count for this tag. For one-piece swimsuits, see off-shoulder one-piece swimsuit.
