This tutorial by SVDL sorted out all my problems with dynamic clothes. Very easy to understand. The main things to remember are to parent your obj to your character's hip when you re-import it and reimport onto an unmorphed Vicky in frame 1. If her body shape has not been altered the imported clothes should fit perfectly. Then just add whatever body morph you want at frame 20 or wherever you have your keyframe for your figure pose.
