I have a review of Levi's Surpeme Curve ID jeans
here. I've also heard amazing things about PZI jeans but I haven't tried them yet.
FWIW, I've also had that problem for years and the Levi's are the first jeans that really took care of it. Certainly pants/jeans with stretch can take care of it initially but they always stretch out by the end of the day and end up being really baggy on me! Grrr.
I love Levi's because they have a few different curves so you can try them on and see what fits best for you!
