Step forward Helena Bonham Carter, an actress who has straddled the spectrum from mildly eccentric to batshit bonkers ever since she morphed from a Merchant Ivory English rose to a Miss Havisham-in-waiting. The 47-year-old has made ‘artfully dishevelled’ a look we aspire to: her hair is always just unbrushed enough, her make-up just slapdash enough, her black lacy ensembles just Gothic enough. In the wrong hands such a get-up would terrify; instead it sends a chill down our spine for all the right reasons.
