Olivia Palermo was looking very Blair Waldorfish at last week's You Know You Want It: Style-Inspiration-Confidence book launch, so it's only fitting she ran into real-life Gossip Girls Leighton Meester and Nicole Fiscella on her way there! So how'd the City star's style compare to that of her Upper East Side counterparts'? Well, obvs we're a smidge biased, but from where we're sitting, she totally held her own! Nothing against Leighton's electric-print dress and Nicole's sleek LBD/blazer combo, but we adored Liv's giant gem-adorned chain necklace -- and her playful pairing of soft (ruffled peasant blouse) with hard (shiny leather miniskirt).
+ Think Olivia hit it out of the park with her girly/rocker glam? Or are you more into Leighton's I-swear-I'm-not-wrapping-paper print? Sound off in the comments and tell us which fashionista had the best style/inspiration/confidence on the carpet!
