There was a time in the 90s when we wore the same pair of beige Levi's corduroy jeans with a grey lambswool jumper and vintage floral waistcoat for two years straight. Never even washed the stuff. And practically never washed (or brushed) our hair. And since good shampoo is super expensive why not do it again? Not washing it is better for your hair than the most expensive conditioner after all... Plus Amber from that Dirty Girls video that's been around for a month now is cool, right? All our most fashiony facebook friends seem to be in love with her. So yeah, our hair is fashionably dirty now, especially fashion ed Britta's. She doesn't manage to look anything like a female 14-year-old version of Kurt Cobain, but you have to work with what you've got... Grunge forever!
