Emily Blunt & Anne Hathaway in Giambattista Valli | 2011 Kennedy Center Honors Gala Dinner

It was quite the fête on Saturday night at U.S. Department of State in Washington D.C.; Anne Hathaway and Emily Blunt (pictured with husband John Krasinski) were just a few of the celebrity and public figure attendees at the 2011 Kennedy Center Honors Gala dinner, hosted by United States Secretary of State Hillary Rodham Clinton.

Anne and Emily celebrated the 2011 honorees, Meryl Streep, Barbara Cook, Yo-Yo Ma, Neil Diamond, and Sonny Rollins at the red carpet dinner, both wearing gowns by Giambattista Valli.

With a side-parted curled up-’do, Emily showed off the asymmetric cap-sleeve neckline on her vibrant berry gown from the Pre-Fall 2011 collection. I’m head-over-heels for the color of this dress, putting aside the fact that it’s gorgeous, it also showcases the modern design. I only wish her black long evening bag wasn’t so distracting.

Anne also carried a black clutch, but hers blended in with her striking strapless black column dress from the Resort 2012 collection.  This wasn’t your typical strapless number, check out that lovely twisted bodice! Anne pulled her hair back tight into a sleek style, but the newly engaged actress drew eyes to her berry freshly manicured nails which highlighted that diamond on her finger. Dazzling in a matching diamond necklace, Anne highlighted her glowing face with a dark berry lip plump pout.

She finished off her look with satin crisscross “3083″ platform sandals by Casadei.
