I'm not sure what Citizens puts into them. Crack maybe? Some special skinny serum? Pajama pants material? Anyway, they are the perfect blend of stretchy, but won't stretch out; soft, but not so weak they will wear out; and fitted. They are literally amazing, oh-so-comfy, and the rise is perfectly mid-rise. If you are looking for a new black pair, let me highly recommend these.
