We're not sure if the crop top got Anna Wintour's seal of approval, but regardless, these style setters all found ways to work them into the Costume Institute Gala's white-tie theme — or did they? That's really up to you — but between Cara Delevingne in Stella McCartney, Rihanna [1]'s white two-piece, Anne Hathaway [2]'s Calvin Klein set, Gabrielle Union [3]'s custom Prada ensemble, and Emma Stone [4]'s Thakoon number, we counted five of them on the red carpet. And, while we're fans of the crop-top comeback [5], we're not entirely sure if they should be coming back as evening wear at the Charles James-themed gala. So, we'll leave it up to you: are you a fan of the dressed-up crop top — and tell us, who wore it best?
