Trouble with cloth simulation on human avatar

Hello all

I am working on cloth simulation and trying to simulate cloth on human avatar. I have a simple humanoid model and working with Kinect. i am controlling model animation by Kinect. Kinect is working fine. My problem is that when i added a custom mesh to this avatar and add physics cloth to this mesh cloth is not working properly with bones, i have added cylinder colliders to bones but still the problem exist. Cloth is working but not in proper way.Sometimes it shrink and sometimes stretched more and i want a stable cloth like this video. what i have done you can see on this video.

Thanks in advance if any one help me.
