Getting that clothing fitting system working for all figures would free up a new world of freedom for figure creators. In that case there would not need to be a single all purpose figure. Wardrobe Wizard and Crossdresser already do this, but it needs to be more integrated and part of the conforming/draping system. A bit like the transfer tool in DS, but much better and usable for all figures. But that is going to be very hard to achieve (for both WM and traditional rigging).

In the ideal world a figure modeler would create a new figure and automatically have all clothing fit and a clothing modeler would have its clothing fit every figure. This would also open up niche markets because the potential user base gets larger (usuable for all figures)
