If you are looking for a boot cut, I really like the Hudson Petite Signature. Macy's has a reasonable selection of Petite premium denim, but it isn't in the petite department, it is with the rest of the higher end jeans. The Hudson Beth mini Boot in Petite was also flattering. Both have a fairly low rise (to me, not to my teenage daughter). They come in a midrise, but it is not Petite.
I loved the fabric for Joe's Jeans and thought their Provocateur style was good for curvy. The Kimmie style from 7 for all mankind was also good, with a more midrise.
I have recently been jeans shopping and it is pretty frustrating. Some of the ones that fit in the store stretched out like crazy over the course of the day. My advice - ask the SA about how much things stretch, and wear anything you buy around the house for a few hours without taking the tags off. You may find you need a smaller size than you found comfortable at the store. I should have sized down in my purchases - I like comfort , but now they need belts.
I have bought a few non-petite pairs and hemmed them, but you really have to be careful of noting where any fading hits so it doesn't look "off". I even have a pair of mini-boot where the slimness in knee hits my calf and looks bunchy - the slight flare to accommodate my (generous) calf muscle hits too low on my calf. Unfortunately I took the tags off before I realized how much it bothered me.
