At a pre-Olympics event in London, Kate Middleton showed off her signature sophisticated style in a gray-and-white plaid flared Hobbs dress — as soon as we saw it, we thought it would be perfect for the office. To break up her look, Kate cinched her waist with a white woven belt and wore matching slingback Pied a Terre espadrilles. Finished off with a sharp black blazer, this ensemble would look totally appropriate at work or at a ladies luncheon.
