To clarify, Poser 13, along with a good number of applications, has made it easier to cross-dress select figures, although the process can be a little convoluted at times.  Unfortunately, texturing has not evolved to the point where you can swap between figures; only in DAZStudio do you have that option.  DSON is no longer usable in Poser 13, and there is no intention by DAZ to ever update the app.  So don't bother importing DAZ Genesis and higher versions unless you have imported those figures with PP2014 and saved them into your Library.
