bugging me in a very strange way..
i put both the pallet in one image by photo shop so you can help me through more information..!!

rendering more MB steps (both deform and transform) might help (try 10/10, it should be enough for catching any motion)

Looks more like a compenetration issue when the mesh is subdivided than anything else really.

..i tried every thing but something strange happened :
i gave a "motion blur" to the shorts and t-shirt( witch were the same mesh) and it got fixed while the body doesn't have such property.. can someone tell me what happened.?!?!?!?!?

then dont use MotionBlur property if you got problems. just motion blur everything without any overrides. it might help too, but just guessing.
