Bumped into this article in Etsy, a very good piece and I think you might also want to read it. :)
And by the way this is how my jeans looked – evidently my left foot is about half an inch shorter (misplacement of bones, as I was told) and hence my left side of jeans is always torn. I didn’t notice it until a few years ago – when I can no longer tolerate my backache and went for a fix, I was told that it was the injury I have had in one of the gym session I had in my early 20’s and that led to the permanent damage on my lower back muscles. I remember that new instructor’s name. Damn you Johnathan from Fitness First.
