One thing I would do is contact the creator of Crossdresser and show her images of your problem.  When you are conforming the clothing is La Femme in default position?  do you have Poser 11 that you could try this in to see if it works there?  As far as I know there is no difference in how they work from version 11 to version 12. It could be something as simple as the clothing do not support the body morphs in the character that you are using.  I've plenty for V4 that ended up being that way.

Not sure if you have this problem solved since your last post, but would be more then happy to see if I can help, I understand the frustration for sure!
