We can always rely on a showstopping performance at Louis Vuitton, and once again Marc Jacobs delivered. There were no trains this season, but the designer kept the energy up with four giant escalators that poured out onto a yellow and white checked arena. The '60s Edie Sedgwick-inspired vibe he put out at his namesake line carried over into his designs for Louis Vuitton — black, white, and acid yellow checkerboard motifs were overt, and the former collection's party girl hairdos got some polish at the latter with bow-bedecked headbands. If you're looking for a way to update shift dresses, matchy-matchy suits, and otherwise mod silhouettes, you can check that off your list thanks to MJ.
