Mary-Kate’s After Party Style
May 9, 2007 by Erin Balser
Mary-Kate was photographed leaving the Costume Institute after part at Gramercy Park Hotel. According to Just Jared, it was hosted by Kate Moss, who was launching her Topshop collection in Barneys on Tuesday. She has a pack of cigarettes in her hand, who which I just say “Tsk!”

Additionally, both Mary-Kate and Ashley were seen bumping and grinding with Mick Jagger (in good, clean post-party fun) at Mr. Chow post-gala!
More photos below the cut.
