Decked out in head-to-toe Mulberry, Kate Bosworth hit the label's Chateau Marmont fête over the weekend in LA channeling elegance and ease. We love that the actress opted for an off-duty army green as an alternative to the LBD, then added in luxe details, like those fab studded Mulberry pumps we spotted at the recent range showing. Appealing to both that chic and super-accessible aesthetic, she finishes with a functional crossbody bag on a pretty chain strap and a few simple gold jewels.
