French fashion designer Sandro threw a private dinner for friends and clients last night at the famed Chateau Marmont Bungalow in Los Angeles. Celebs including Emmy Rossum, Annabelle Wallis, Emma Roberts, and Jaime King (pictured above), came out Thursday night to celebrate the gorgeous, Parisian-chic line.

Actress Emmy Rossum, an affirmed fan of the designer, wore Sandro head to toe. Well, almost head to toe. “Clavicle to ankle!” She declared, wearing Stuart Weitzman shoes. Rossum cited the brand’s sense of relaxed chic as her reason for devotion. “(Sandro is) easy to wear for every day. It’s for the girl who’s confident but relaxed. I like it a lot.”

As the sun set, dinner was served as glowing candles and heat lamps illuminated the grove of palm trees surrounding the poolside party. Guests were treated to a three-course meal including kale and feta salads, crispy bass, and thyme roasted chicken with caramelized cauliflower.

Catching Fire actress Jena Malone surprised guests with an unexpected performance. After her set, the actress/musician beamed, “This was the best audience I have ever performed in front of. . . they were great!”

Jaime King was taken aback by Malone’s surprise performance. “It was so beautiful,” the model/actress said. “It was like Mazzy Star-ish…really really beautiful.”
