Blair Waldorf plays the ultimate queen bee at Gossip Girl's prestigious New York City high school that is based on a real school on Manhattan's Upper East Side — Nightingale-Bamford. The uniforms worn by Blair, Serena, and Jenny are surprisingly lax on the show, as the girls customise them to suit their preppy, bohemian, and edgy personal styles. As for Blair, her collection of sharply tailored black prep-school-style blazers is central to her character's upper-crust influence.
