well i haven't tried it,but there is a plugin for 3dsmax by digimation called "stitch".it's really quite neat,it lets you lay out patterns just like you would for real clothing,the software then stitches it all together and conforms it to whatever body you choose to apply it too it also takes care of the physics,ie how the cloth falls wrinkles etc. as i said i haven't tried it but i have seen it used and i strongly suspect others are using it judging by the "look" of thier work.
