Michelle Obama has certainly been taking full advantage of her summer vacation. This weekend she left Martha’s Vineyard wearing one of her favorite color combos: black, white, and silver. She paired a sleeveless top with a full skirt, metallic flats, and her ever-present stack of beaded bangles. The FLOTUS then arrived in New Orleans wearing a muted floral dress and another pair of shiny flats, this time in a neutral shade of green. She accessorized with gold bracelets, hoop earrings, and pulled-back hair. See the full looks in the Michelle Obama Look Book.
