When I lived in Dallas I had a girl at Neiman's that I went to, but that's a long drive for just a pair of jeans now. She was awesome- she'd take one look at you, ask what you were looking for then bring half a dozen jeans to the dressing room that pretty much all looked great.
My body has changed slightly since having DD, so while my old jeans are okay I'd really like one pair (okay, 2 pairs) of really great great fitting jeans and it's been so long since I've had to buy any that I'm pretty out of touch with how certain labels fit.
So, rec the place/person you go to for great jeans help!
Oh, I've been to Hem but they really weren't that helpful (ex: they brought me Joe's Honey [curvy fit] when I have a more Twiggy [long legs, little waist definition, flat butt] body) but that was 3 years ago so they might be better now.
I've also bought cheaper jeans like Calvin Klein and Target but they were never right so I've given them all away.
