Leave it to Blair Waldorf to scheme in style — this week's episode of Gossip Girl had Blair planning the studious Nelly Yuki's demise. You would never know that Blair wasn't the resident academic over-achiever in this preppy ensemble, though. From her perfect saddle shoes and argyle sweater to her prim little gloves and headband, her look practically redefines "polished." If only she spent less time conspiring and more time actually hitting the books . . . but then she wouldn't be Blair, would she?
