With Poser Pro 2014 or 11, you can rig Genesis 3 clothing to work with your Poser figures. I do that all the time because DAZ unloads some really well-made kit for extremely low prices in its sales, and I export the obj and rig them for Pauline, Paul, and Genesis 2 in Poser. And I just did the same for Maisie. Try doing that the other direction. Poser is a tool, not just a render engine.
