This is a very tough choice, but who wore it better? Cameron Diaz wore this Alexander McQueen dress first back in 2009 at the Golden Globe Awards. She was the last to arrive on the red carpet so all eyes and cameras were on her in this form fitting satin dress. And Kate Middleton's Maid of Honor, little sister Pippa, also had all eyes on her when she wore the same dress to the Royal Wedding. For her dress however she opted for an ivory and lace version, with dozens of buttons down her back. And she looked great too. People are talking about her dress just as much as her sister's wedding gown!
