Where: Walking around Los Angeles.

What: A Vince silk georgette dress and Handy burgundy leather wedges, both from Isabel Marant Spring 2012.

Why: Casual chic can often be tougher than a red carpet slam dunk. Bosworth nails it with this easy, but still pulled together patterned dress, simple wedges, and sleek metal cross-body envelope. Who looks this good walking through a parking lot?
