Okay, so I went back and zeroed Tyler and... well pretty much the same thing happened. So then I realized that I need to remove IK. So I did. Better, but still not perfect. However. I can conform the clothes now, but to do so, I have to conform them to Tyler then Zero them in order for them to fit right. Which makes me think I'm still not doing something right.
Anyway, working on a suit for Tyler. Needless to say, I have a few... refinements to make.
