The stars turned out for Max Mara and W Magazine's cocktail party to honor the Women in Film Max Mara Face of the Future, Rose Byrne.

The honoree sparkled in a navy sequined V-neck dress with crimped, textured hair. "Penny [Lovell], my stylist, and I picked it out," the Neighbors actress, 34, told Us Weekly at the event held at Chateau Marmont on June 10. "I liked the sequence of it. It really popped, and it was a cocktail number, which is relaxed too."

On hand to fete the star was Sophia Bush, who opted for the a printed T-shirt style Sportmax dress with contrasting bright blue Casadei pumps and Vita Fede jewelry. The Chicago P.D. star swept her newly dyed hair into an updo, but said she's still on the fence whether blondes really have more fun. "I think I have a pretty good time all the time," she told Us. "I'm practicing constant gratitude so life is good for me."

Krysten Ritter ditched her usual wild prints for a black and pink Sportmax polka dot silk dress. The Veronica Mars actress, carrying an Edie Parker clutch, wore her dark hair in smooth, loose waves and sported natural makeup with just a strawberry lip color.

Pregnant Stacy Keibler stood out among the neutral and pastel colors in a Day-Glo green one-shouldered M Missoni dress, which hung loosely around her baby bump. With side-parted smooth hair, the mom-to-be added a contrasting peach lip and matching blush.

Scandal actress Darby Stanchfield rocked a sexy pleated sheer top and gathered skirt. The redhead highlighted her teeny waist with a skinny metal belt and carried a black clutch.

Victoria Justice, in Aldo ankle-strap heels and carrying a mirrored Aldo clutch, opted for a pale pink tank dress with polka dots by Sportmax. The Nickelodeon star left her long and loose with textured waves and carried a mirrored clutch. Pretty Little Liars star Troian Bellisario also styled her hair in a middle part, but took more of a risk with a lace dress featuring an embroidered floral motif paired with rose-gold Aldo heels.
