I did find a solution for the panties. When they are added to the 'scene' with Eve, instead of 'conforming' them to her, you can assign her hip as 'parent' to the panties 'hip', her buttocks as 'parent' to the panties 'buttock', etc. This after using x,y,z parameters to adjust them to the proper position. After that, they move with her and do not distort as they do when 'conformed'.
