Michelle Obama went from Martha's Vineyard to Ted Kennedy's funeral and then back to the White House over the weekend. She wore black dresses the whole way through, as well as some pretty neat flat sandals we hadn't noticed before, when she returned to the White House yesterday. See her three new looks from the weekend in the Michelle Obama Look Book. Update: The sandals are by Maison Martin Margiela! It's her first public Margiela on record and makes up for last week's Crocs.
