Look who's color blocking! Following in the footsteps of celebrities like Freida Pinto, Emily Blunt, and Sarah Jessica Parker, Pippa Middleton worked the vibrant look on her way to a hair appointment. The royal-in-law paired Paper London's Mondrian-inspired sweater (currently sold out online) with Goldsign's dark denim "Lure" skinny jeans ($240 at, topping off the style with her signature Modalu bag in black leather.
