Depending on how much money you want to spend, I love AG Jeans.
I'm sort of biased because I used to worked there for like two years and have like a million pairs of jeans from there, but there are so many different fits that it's impossible not to find something that will fit you and that you'll love. If you live close to one of the actual AG stores, I'd definitely say to check it out, as they all know the product and can get you exactly what you're looking for!!
Besides that, Rich & Skinny's and Sass & Bide are awesome!!
