Leather trousers, the ultimate rock chick piece, are Hollywood's latest expression of the dominatrix trend that kicked off on the catwalks with Christopher Bailey's collection for Burberry Prorsum. Surprisingly versatile, they can be dressed up with a sheer blouse and tuxedo jacket as seen on Kate Moss, or dressed down with a slouchy jumper and chunky heels as per Mary-Kate Olsen and Juliette Lewis. Few people on the planet can get away with Elle 'The Body' Macpherson's double leather look, so steer clear unless you're blessed with a lanky frame as leather can be clingy. If you want to dabble in the leather department but are worried trousers just aren't for you, try another celebrity favourite, the cropped biker jacket.
