This isn't my fist pair of this particular style of jeans...but my old pair didn't stretch NEARLY as much as these do.  My old pair (size 30) were so tight I couldn't button them up, so I bought a 31. They fit great as soon as put them on but after just a couple of hours, they're incredibly stretched (like, two inches) and the flattering fit goes the way of giving me dumpy [...].  I might try washing them in hot water to see if they shrink up a bit, or maybe kill some of the spandex. Other than that, I still love the style.  I am short-waisted, so these fit perfectly.

As others have said though, these are short-inseam jeans...so buyer beware!
