The Loin is AsHipC2, by As Shanim.  As Shanim is also Awful Soul and Aery Soul.

He made it for Vicky 2...I think, and has since converted it for V3.  

I then fit it to M2.  It was'nt too tough, but took me a week or so.  I did'nt add any magnets, so most of the adjustments were just Size, and Transform.  If you have Poser 7, I think I could write you a pose file that would help.
