It was 1994 when Princess Diana strutted into the Serpentine Gallery looking like the Royal Family's worst nightmare and everyone else’s dream. It’s hard to imagine a fashion moment more impactful than her little black revenge dress. She wore it the evening that Prince Charles admitted to the world that he had been cheating on her. For this video we spoke to, Eloise Moran author of The Lady Di Look Book, who says black would have been a bit of a no go colour for the royal family. But once you’ve been cheated on you should probably be allowed to wear whatever you want. And according to Moran her dress sense definitely evolved post divorce as she traded the frills and bows for mini skirts, shoulder pads, red nail varnish, high heels and athleisure in her 30s.
