I've used OBJ2CR2 and swear by it. It's easy to use once you get a little practiced at it.
You make your mesh and import it into poser. It has to line up with the figure when it's absolutely zeroed.
Call up a template from the OBJ2CR2 props folder that works for the figure. NOTE: You can MAKE your own templates for ANY figure, even ones you MADE yourself. Once you have a template you want to reuse, save it to the library. This saves tons of time because you DON'T ever have to repeat this step again!
Philc has tutorials on how to adapt OBJ2CR2 at his site:
http://www.philc.net/store_Python_utilities.phpSelect the mesh you want as a conformer and click run. NOTE: No grouping need apply! You don't have to do any grouping, the OBJ2CR2 does it automatically. Run it.
BAM! You have a new figure. You might need to tweak JPs because the original figure's JP might be so tight they just won't work for clothes.
I can't save the world. I CAN save money on Poser stuff. Buy stuff here! LOLOLOLOLOL
Ideas are free. Time to act on them is priceless.
