It wouldn’t be Gossip Girl if there weren’t parties. So of course Chuck is throwing a party in Season 4, Episode 15: “It-Girl Happened One Night.” And the Gossip Girl gang looks flawless as always.

The palette of the episode is warm, creamy, golden and beautiful. For her new (and we’re guessing important) assignment at W, Blair looks deliciously professional in a DVF blouse, plaid Joie cape, and delightful bias-cut skirt by Rodarte. What could easily be perceived as a crazy-straw of patterns works surprisingly well in Blair’s look.

Even whilst lounging (likely day-dreaming about Ben), Serena looks elegant in a simple Nili Lotan button down with knee-high American Apparel socks. But she really knocks it out of the park with the classically elegant Ralph Lauren gown (which flaunts her assets, natch) she dons to Chuck’s fete.

Blair’s other outfits in the ep are nothing to sneeze at either. Her lovely Marchesa gown screams old world glamour, and the Blythe bracelet and Swarovski earrings with which she pairs the number are the perfect accompaniment. We’re totally crushing on her business look: The bronzed Balmain blazer is gorg, and the understated Stella pants are a beautiful pairing.

We can’t wait to tune in tonight to watch these dolls come to life!
