If leaving it late is your thing, we've got a Halloween costume-fix to die for. Actress Ashley Madekwe looked scarily good in this Joker get-up and the best bit? You can get the look with a white shirt-dress, some Stan Smiths and a fancy-dress nurse's hat. Nip in your waist with a stretchy 80s belt, add a green wig and finish with a slash of red lippy – probably the only time it's acceptable to get your boyfriend to apply it.
