Oh, I didn't mean sliding the sleave along the arm, that would require the joint operated morph chanel that Nerd has worked out. I meant that it should rest or hug the top of the arm. In the sleave morph it is most evident that the sleave is set with the arm centered in it, giving the illusion it is somehow hovering over the arm, if it was set so the top of the sleave was "in contact" with the top of the arm with the empty space of the sleave only below the arm always, this would work for any poses that weren't completely upsidedown.
