Snapped today while filming Gossip Girl on the Upper East Side, Leighton Meester's character Blair Waldorf looks like a modern Carmen Sandiego. Perhaps she's doing a bit of sleuthing?

It's interesting to note the use of plaids, both small and oversized. It can be difficult to mix patterns, however show stylist Eric Daman mixed this look with perfection. Did you catch that she's carrying Chanel's Mademoiselle bag, which co-star Blake Lively just happens to be the face for (shockingly)? Nice synergy.

Aside from her Bailey Button UGGs (cut her a break - it's SUPER cold in the city today) - how do you feel about the look. Hit? Miss?
