Weighting in Blender problem.

[mimi Duffield]

Hi. I would like to know if there is a way to reduce distortion after changing the shape sliders of my mesh body in blender. I created a close fitting accessory and was able to reduce distortion when changing the pose with "smooth" in the weight options. But it gets distorted when I change the cleavage shape of the mesh body. "Smooth"  doesn't affect my mesh. I tried weight painting and still no effect.
