I might give Crossdresser a try. I wonder if I can use WW to convert to, say, V4, and get away with just getting Crossdresser licenses for V4 and LaFemme.

I have used the Fitting Room, but I find it difficult to get good results. WW is super easy in comparison, and the clothes seem to fit better in extreme poses. Maybe I just don't know how to use it right.
