Last night’s YSL-sponsored Metropolitan Opera opening gala looked more like a couture fashion show than an opera, with stars like Diane Kruger, Eva Mendes, Leighton Meester, Emmy Rossum and Ginnifer Goodwin each in hand-picked Yves Saint Laurent. Diane Kruger’s hot pink dress was custom-designed just for the event. And she accessorized with her date — and long-time boyfriend — Dawson’s Creek alum Joshua Jackson, who joked to PEOPLE, “In general, I’m not very glamorous. Tonight, I feel extremely high-glam. Tonight we’re glamorous.” Emmy Rossum couldn’t contain her excitement about selecting her little black dress for the premiere of La Fille du Regiment. “I got to go to the showroom and pick!” she tells us. “I’m like a kid in the candy shop!” Ginnifer Goodwin will remember the evening as the first time she ever wore head-to-toe Yves Saint Laurent — and now, the Big Love actress says, she is “obsessed with it.” Click here to check out all the stars’ fashionable looks from the opera and more — and don’t forget to vote for your favorites!
