Check out Nerd's "Conforming Clothing Figures." The URL is: www.theworks.com/~nerd/Tutorial/ConformingPrint.htm. Also, check out the Tutorials section here on Renderosity. Used to be a couple of good tutorials on this topic there. Nerd didn't place any restrictions on redistribution for his tutorial, so if you can't find it, let me know and I'll e-mail it to you.
