Except for the actual model-making of the clothing, you can do the entire conforming process inside Pro Pack. Import your clothing mesh, go to the setup room, load a figure's joint parameters from the Library, group your mesh (Pro Pack has an auto-group feature), and you're done, aside from the final step of endless tinkering and fine-tuning to get it perfect. If you aren't too picky, you can have something conforming in less than three minutes.
