Sarah Jessica Parker attended the New York premiere of Harry Potter and the Deathly Hallows as a big fan – or rather her children are – of the franchise. For the occasion Sarah Jessica chose a dress from Oscar De La Renta’s resort collection. She teamed the pretty strapless navy and blossom watercolour print chiffon gown with a black blazer by Salvatore Ferragamo. The only issue I have here is with that Ferragamo bag – it doesn’t go!
