Ordered these in a 12 first and they were too big, so exhanged for a 10 .. they fit perfectly.  I know I am not a 10 so they definitely run big.  I also saw other reviews that thought the the "long" were too long.  I didn't find that I am a little over 5'10" and thought they fit fne.  Overall a good pair of jeans.  The sytle is "work" so I thought they would be too casual, but they look like regular black jeans.
