Here's two pictures to show the dirt on the inside hem that I roll up. I wear a 34 leg, but because the jeans stretch so much from wearing them every day, plus the fact that they haven't shrunk yet, makes them sit a little lower than usual. This means that in the end I needed to fold them hem up twice instead of the usual once. You can clearly see how dirty they became from just and every day wear. A little gross really, but all in the name of fashion.
