Sleeveless dress can be used together with detached sleeves, since sleeveless dress only refers to the torso garment, and do not take detached sleeves into account.
Do not confuse this tag as a "catch-all" tag for all dresses that simply leave the shoulders bare.
If the dress has a low and wide-cut neckline and has attached sleeves that sit on the arms instead of on the shoulders, it is an off-shoulder dress.
If the dress has no attached sleeves and has no support of the shoulders (ie. halternecks, shoulder straps, etc.) to keep it in place, it is a strapless dress.
