My sophomore year in college, I had the distinct pleasure of living with the boyfriend of a Gap associate. (On a side note: I've never actually been friends with people who work at Gap, just people who date people who work at Gap. Hmm.) It was through him and his borderline obsessive chatter about Gap jeans that I was introduced to the concept of 'raw denim,' or premium jeans meant to be worn for long periods without washing. He had me convinced when, by the end of our first term at school, his pants had that effortlessly cool weathered look, with knee wrinkles and wallet marks that made the jeans distinctly his own. My olfactory senses and those of my housemates, though, can verify that he definitely hadn't seen this tutorial on how to keep those stylish pants from smelling like they'd been worn for three months straight. For the sake of warding off any kind of dirty hipster reputation, take a quick look at this video from Apartment Therapy, clear some room in the freezer, and be prepared to call yourself eco-chic from all that laundry water you'll be saving.
