I've been playing with stretchy fabrics in the Cloth Room, and I'm not having much luck with stretching. I use Serge Marck's technique of flattening the figure and "inflating" her into the clothes to make them fit, but when I tried "shrinking" the clothes to make them stretch, they only shrank to a certain point, then stopped. This is with all kinds of collision on.

I'm guessing I need finer mesh, but the dynamics are such a mystery that I'm wondering if the problem can be fixed there. What I am trying to do is get the form-gripping quality of jersey rather than the gap-spanning effect of spandex. Specifically, a tight jersey dress clings in the cleavage of the rump, and when I stretch skirts, they span spaces like that. Any ideas?
