Sophia Bush is always a familiar face at Fashion Week — remember when she wore five outfits in one day last fall? — but this year, the One Tree Hill star seemed to defy space and time by making it to more shows than anyone! (We stopped counting at 10!) From her sexy turn at Herve Leger, which she called “a really, really sensual line,” to turning up to a dinner honoring Rihanna in a Ports 1961 one-shouldered dress, to hitting Catherine Malandrino’s show in one of the designer’s purple dresses, Sophia was perfectly turned out everywhere she went. Having sat behind her at more than one show, we can vouch first-hand how flawless she looks (especially her skin!). But we think we’ve stumbled onto one of her secrets for looking so good — we hear she stopped by the Spanx Suite while in town and stocked up on slimming undergarments, including the new Slim Cognito Cami. After all, those fabulous dinners and cocktail parties catch up to everyone!
