I have had this problem of goofy geometry, and I have done quite a bit of work to clean it up. If you had seen in what state the dress was when I converted it from poly to subs!!! I had to re-stitch all the edges and there were pieces of geometry so folded that I didn't know what to do with them. Does anybody have any suggestion on how to avoid this type of problem?

By the way, thanks for the comment, I will try to refine the geometry and see if I can eliminate some of those edges. Also, it is rendered at the lowest anti-aliasing possible.
