When I encounter something like this my solution is to open a new window and dress the character as I want, then I apply the different poses that I plan to use and save him and that pose as a subset, yes each pose and subset is saved to a folder. If I recall The Dude is an old poser character. Then I import the the subset character and pose into the appropriate scene and viola! No problem. I know someone else has a different solution.   This process might work in lightwave as well.
