Last night's Metropolitan Opera gala premiere of Jules Massenet's Manon didn't just bring about gorgeous vocals and dramatic scenery onstage. Offstage on the black carpet, a stylish crew of celebs dressed to the nines, all wearing superchic iterations of Yves Saint Laurent no less. Chloë Moretz chose a sophisticated tiered midnight-blue gown, complete with a black velvet bow and a black choker; Amber Heard exuded her signature sultry glamour in a silky black number; Emmy Rossum opted for rich magenta tones and a bold embellished choker; January Jones wore a sleek drape-neck creation with sexy back cutouts; and Emma Roberts kept it playful and fun in a slick jumpsuit. It certainly was an evening filled with elegance and cool takes on YSL's classic designs, but now it's time to weigh in: who do you think was most fab?
