MIchelle Obama and Jill Biden popped over to a NASCAR race in Florida this weekend to serve as Grand Marshals, and received a rather, um, lukewarm welcome. People actually booed them, which you can hear on this video on Gawker. At least she looked good, in spite of the boos, wearing a Maison Martin Margiela top. Mrs. O reports that the FLOTUS' Margiela top was last seen at an event in 2009. You think the NASCAR fans just hate edgy Belgian fashion? Yeah, we didn't think so either. But rock on and keep shopping your closet, Mrs. O.
