Crossdresser had a module that would add the figure morphs to the clothing. I dont know how many morphs they offered but it was pretty good. I didnt know they had them for M4, last time I looked it was V4 only.

Lyrra offered a set of magnets to product the morphs in clothing, but thats more work to convert the magnet set to a morph.

I would post your fit problem at their website and see if there is some parameter that might get it better. http://www.evilinnocence.com/xd/
