Been playing with this for the past couple of hours, and I have to say this shows good potential, I have a skirt rigged and conformed to Genesis, it also has the active morphs in Genesis auto-generated in the skirt, and on top of that it's now draped around those morphs.

I only have the basic plugin so I can't edit the cloth settings in DS, but even so I'm getting decent results with trial & error in my text editor, like this I dare say I could even make a hybrid dress, where the top conforms and the skirt part drapes.

Attached pic shows Genesis and the skirt on the left, in the middle we are on frame 30 where I've posed and morphed Genesis, and on the right is frame 30 after I've ran an animated drape.
