I read this article from the SF Chronicle today about Levi's new Curve ID line, which has three fits:

"Instead, Levi's analyzed body scan images of 60,000 women around the world and came up with a new fitting system, organized around three basic body shapes: slight curve (straighter figure/flatter fanny), demi curve (evenly proportioned hip and seat) and bold curve (smaller waist, larger seat). The shapes are based on a formula developed by Levi's involving waist, hip and seat measurements."

Sounds intriguing if it works out. The article doesn't say when the new jeans will be rolled out, but implies they're available now.
