I read about this fad somewhere recently, but I can’t remember where. A couple minutes of internet research has yielded what I was hoping for–Nudie Jeans. They claim that jeans share your soul or something like that, and that you shouldn’t wash a pair of their jeans for the first 6 months, at least. You can read what they say here.
I just don’t think I could do it, no matter how much “personality” my jeans were developing. If by personality, they mean stench, then I’m not interested. Plus they’re like $200 a pair, so I’m thinking I’ll stick with Target.
