Animations for Cloaks?

I tried one cloak and it seems to be just fine except that 1) the animations of my hands cause my elbows to show through the fabric of the cloak and 2) flexiprims do not collide with my body.

So does anyone know is there any animation overrider that makes the hands of my avatar to stay still and not constantly change position nor showing through the cloak? It would be good also if the hands did not swing through the cloak while walking.

Maybe... go to the loft and try it out on the display... the walk is the last item in the sequence.
