Pippa Middleton treated herself to a bit of retail therapy today after work in London. She is fresh off a fashionable five-day stretch in her office that saw her decked out in chic dresses from Zara and fun summery tops. Her sister, Kate, is likewise setting trends with her rare public appearances. The beige Reiss dress Kate Middleton wore to meet the Obamas on Tuesday has also sold out! The worldwide fame that Pippa found following Kate's wedding to Prince William last month has even prompted rumors about a Middleton presence on TV. There are rumors of Pippa Middleton appearing on the OWN channel, Oprah Winfrey's new network, or some sort of tribute to her on the next season of Glee.
