The search for the perfect jeans is ALWAYS on, and I own more than anyone I know. Most of them are sitting in my closet, though, and I alternate four of my favorites. The jeans I swear by are Levi's Premium Superlow. They always fit perfectly. I've definitely stocked up on those, because they're difficult to find, and they're not sold in any store in Alaska. I have virtually NO butt and wear a size 0 L...Diesel always fits really well, too, and comes in nice long lengths, so I never pass up a chance to try out some new cuts by that brand. Also, I can't stand Abercrombie and Fitch....Still, their jeans fit super well, they're inexpensive, and cut narrow in the hips, the O L is just right the length after a washing, so I own several of their jeans too. I've tried J. Crew jeans, but they're kind of uhm......roomy in the crotch? It's like they're made for women with a poofy crotch disorder, but the rest of their pants are fabulous. Yanuk jeans- the six pocket boyfriend jeans- fit well in the back and their pockets aren't placed so low that they give the illusion of Texas- butt...Long and flat with handles on the side. I could actually go on and on about jeans....
The pants that fit the best, though, aren't jeans, but cut like jeans. They're from the Serious clothing line, and they're a stretchy cordoury pant with buttons at the hemline. They give me the butt that all the squats in the world won't.
