actually, she's an lf2 figure, so I tried to conform her first, then tried the tool, which at first had wrong pose, I corrected pose, then loaded sweater on and tried to conform, no work. then I went to cloth room, clothified sweater, put her in first pose, then second, slightly different, and ran sim.  sweater dropped off.

I know they look alike but top is first position and second is frame 30, but that's what happened.
