Liberty Ross in Stella McCartney | “My Valentine” Video Premiere Hosted by Paul McCartney & Stella McCartney

The beautiful Liberty Ross was among the A-list attendees at the Stella McCartney soirèe on Friday night. The event was in honor of Sir Paul McCartney’s music video premiere for his new single “My Valentine” at Stella’s LA shop.

Liberty showcased her toned figure in one of my favorite dresses from the Spring 2012 collection.

Sure, everyone is wearing the swirling patterned dresses — but that doesn’t make them any less interesting. This red and white one-shouldered design was one of my favorites from the collection and I love how it looks on Liberty’s long and lean frame.

Above everything else, I’m totally digging her layered shoulder-grazing haircut!

Liberty completed her look with studded back leather ankle boots. They’re a bit heavy with the dress, but they’re cool anyway.

You can next see Liberty on the big-screen as she plays the mother of Snow White (played by Kristen Stewart) in “Snow White and the Huntsman”. Liberty’s husband, Rupert Sanders directed the highly anticipated action-fairytale.
