...just checked the conforming clothing tut I bought a while ago.  The vendors name is markdc.  Forgot to mention that the tut is a series of videos, so it has a 'hands on' classroom feel.  He uses Max in the videos, but you can use most any modeler.  I also bought his Quick Conform product which is pretty nifty.  Here's the link for the clothes modeling tut:

Regarding PhilC's tut this is what one review said:  "When I was just beginning to learn about modeling (still am), this CD was instrumental in finding my way through the learning curve. I still have a journey in front of me, but I would recommend this CD to anyone starting their way down the Poser road."  Here's the link to PhilC's clothing tut:
