Pippa Middleton hit the streets in London this morning in her latest chic outfit as she made her way to meet friends at Harrod's for lunch. Kate Middleton's younger sister was decked out in head-to-toe blues and denim, which made for a slightly edgier look than her trademark Spring dresses. Pippa last put her fashion sense on display when she was on a weekend getaway in Spain. Pippa and her ex, George Percy, along with another of her girlfriends spent a few days in Madrid, where they shopped, took a boat out onto a lake, and partied late into the evening. The gang wrapped up the continental fun and headed back to the UK Sunday. Now that all the excitement over Kate and Prince William's wedding has wrapped up, Pippa's easing back into her own work life. She's a part-time employee at her parents' company, Party Pieces, and writes a blog for the business called The Party Times. Pippa spends the rest of her week working for another event-planning firm called Table Talk.
