I would go with the color version on this one, since you've got some interesting colors going on. In either version, though, you'll probably want to do a little more PP to show the texture and light on the clothes, though, since Alpha is right-- the clothes don't look very interesting, and generally lack detail. If you can shoot this again, I'd try with some more fill light on the clothes (or lighter colored clothes, if you have that option,) or possibly a raking light across the clothes to show some texture and make them interesting.
