Gap in the 'curvy' styles and Ann Taylor Loft in the 'Julie' cut. They aren't perfect (I have a HUGE discrepancy between my thighs and my waist), but they are the best I've found.
I also have a couple of pairs of North Face shorts that work well. I think because they are 'hiking' shorts, they were cut with a little more room in the leg, so they fit me as regular shorts fit straighter shaped women.
