I know this is against the pure Poser render rules, but the easiest way around this is to render twice...once with the clothes and the figure, and once with the offending figure parts made invisible. Take into your favorite 2d program and put the two graphics together, and erase and blend until you have the look you want. I've had clothes that conformed perfectly, and clothes that didn't. After many hours of doing the Poser dance, sometimes it is worth doing a short cut and sacrificing my pride about pure Poser renders. Just a thought.
