The whole concern about smell or the jeans getting dirty is just speculative. As, its inevitable that all clothes will eventually get dirty and smell after enough time or wear. I have 2 pairs of Pure Blue Japan 005s and a pair of Samurai S710s. None of them ever really smell (febreeze is great), and If i have get the feeling they're getting a bit nasty, then I just give them a cold soak and hang them outside to dry. It works great, and you're free to wear your denim as you see fit. Also, you can wash your jeans anytime you want, just know that its going to affect how your jeans will look over time. If you want them to fade to a very light color then wash them as often as any other pair. But if you like a ton of contrast that great "if those jeans could talk" look, then keep the washing to a minimum. I also, do all my repairs on my jeans myself. I think it gives them more character. I'll post a pic of my 2 year old PBJs later this week when I get some time to take a few good shots.
