I recently made this clothing illustrated in the attached image using zBrush 4R7 and Blender 2.77a.  I am having a problem trying to weight paint the clothing to get the proper movement with the armature after I transfer weights,  Notice the arms and the waist on the the image.  I understand the weight painting method or so I think but I am not getting the desired results.  Does anyone have any suggestions?

Thanks
Al
