Could Pippa soon be joining the ranks of Kate Middleton and Michelle Obama when it comes to selling power? Apparently, the Duchess of Cambridge isn't the only Middleton who can move merchandise in shockingly short periods of time. According to In Style, Pippa Middleton wore this NW3 by Hobbs red linen dress to Wimbledon this morning and it is already sold out at two different e-commerce sites. But then, we realized US Weekly spotted her shopping yesterday in the same outfit. Guess this means she's back together with her ex-boyfriend who she was sitting next to at the tennis match!!
