The Duchess of Cambridge's frock and hair do were not the only talking point at the Art Fund's Museum of the Year bash on Wednesday night (6 July). The Turner-prize winning artist Grayson Perry's alter ego, Claire, met her doppelganger, Caroline Worthington. The chief executive of Bexley Heritage Trust in south London, shared curatorial small-talk while attracting admiring glances at the pre-awards drinks. Grayson later tweeted a pic of the pair of power dressers. For the record, Claire wore an art-deco inspired bespoke frock, Caroline was in Scandi-minimalist by Cos. Meanwhile, the former Kate Middleton was in a full-length, off-the-shoulder dress. The sartorial effect somewhat overshadowed the Serpentine summer party down the street, another swanky event that night.
