Clothing Belly dance dress

I was trying to find solution for busty model, i gave a try to find busty model and make my clothes fit on her body but when i did import into VAM, VAM seems to be creating joints which pull the dress closer. Only option for me is to leave enough clothing material but sometimes not possible with every design but i am trying to do it now for some of the dress. you can adjust collision trigger in physics tab, stiffness,and distance scale setting and hope that may help. I have taken your input and will be leaving enough clothing material or turn into elastic to make it fit for busty models .
