I am old. I know this, because Frances Bean Cobain is a muse of Hedi Slimane. It's over two years now since Cobain posed for one of those stark, confrontational, black-and-white portrait series for which Slimane, fashion's so-called "Prince of Darkness", is famous. The pictures are incredible, I don't know how I missed them.
Frances Bean is mesmerising, a pillow-lipped avenging angel, staring at the camera like it's bringing the apocalypse, no trace of fear in her uncanny eyes. This, you think, is a girl who's seen things. This is the girl Kristen Stewart is approximating when she tries punk-rock nonchalance on for size.
It makes sense for Slimane to have shot Frances Bean; he's been on a grungy spree at Saint Laurent womenswear since he got there, a 90s-redux that's seen him use Kim Gordon and Frances' mama, Courtney Love, in ad campaigns. This doesn't make the portraits of Frances any less disquieting. In my head, Frances Bean Cobain is not a model. She's a baby.
I came of age in the latter half of the 1990s, the very era Slimane is harking back to in his latest fall and resort collections. I knew Frances Bean back then, of course, but I knew her parents better. I spent a lot of time with her Dad and the rest of his band after school in my bedroom.
