Michelle Obama wore a structured Peter Som shift dress with a painterly striped top and brocade skirt to christen the U.S. Coast Guard cutter Stratton in Pascagoula, Mississippi, last Friday. On Sunday, she wore a blue petal-print Moschino dress (last seen in May 2009), which she paired with pewter flats, black shades, and a boxy white bag. See both looks in the Michelle Obama Look Book.
