This weekend was rather a glorious one in the world of celebrity fashion. As hype surrounding the big-screen version of Gillian Fllyn's novel Gone Girl reached fever pitch, a pregnant Rosamund Pike dressed in Altuzarra and joined Reese Witherspoon (resplendent in scarlet Calvin Klein) to open the movie at the hottest ticket in town during New York Film Festival. Meanwhile, Cate Blanchett was working her magic over at Zurich Film Festival, courtesy of a midriff-baring retro navy ensemble. And let's not forget new bride Amal Alamuddin, who looked fab on the arm of George Clooney in Venice, in a Giambattista Valli couture design.
But the style plaudits weren't reserved for the red carpet and official events. Over in LA, Heidi Klum worked a low-key sunny vibe to perfection in jeans and a tee while Jessica Alba scored points for her transitional autumn wardrobe (cue: trilby and an arm-less knit) and Victoria Beckham looked flawless as always in a green leather jacket and stilettos, as she popped by the Big Apple.
