It's gone a bit grunge-glam in celebsville, as inspired by fashion's favourite leather-jacket loving designer, Rick Owens. Thrown over just about anything (see Mischa Barton), a leather jacket gives that all important rock 'n' roll rebel edge to an outfit. Shrunken styles that leave no room for a woolie (unless it's fine knit cashmere) are sexy in a bad girl way, as seen here on Cat Deeley. And don't be restricted by black… Molly Sims and Hayden Panettiere sport the look in red and sky blue respectively.
