I HAVE WORN LEVIS FOREVER, SPECIFICALLY 545'S. I LOVE THEM AND HAVE ONE PAIR IN EACH COLOR, JUST BOUGHT SOME MORE AND THEY ARE NOT THE SAME MATERIAL, THEY ARE THIN LIKE A CHEAP DENIM AND THEY STRETCH OUT, THE WAIST STRETCHES OUT SO YOU THEN START GETTING THE PUCKERING, SO IM THINKING I SHOULD ORDER A SIZE SMALLER SO WHEN THEY STRETCH OUT THEY WILL BE THE RIGHT SIZE ???????  ITS A SIGN OF THE TIMES, EVERYONE IS CUTTING CORNERS, MAKING THINGS CHEAPER BUT CHARGING MORE.
