Mary-Kate and Ashley Olsen braved the rain and windy weather in NYC yesterday. The sisters were back out in the city after also being spotted catching a ride together on Tuesday morning. They kicked off the week in a more glamorous fashion, however, when they joined the rest of the amazing famous faces at Monday's Met Gala. MK and Ashley went with very different looks for the big night, and inside the Olsens cozied up with Christian Louboutin amid the crowd ranging from Gwyneth Paltrow and Beyoncé Knowles to Gisele Bundchen and Tom Brady. Mary-Kate and Ashley got back to work following the fun night out and their focus on business is clearly paying off since The Row clothing line is doing an estimated $12 million in sales annually and they recently celebrated their TEXTILE Elizabeth and James brand with a party in the Big Apple.
