Blair Waldorf’s Valentino Silver Sequin Mini Dress, Gossip Girl S4 E3 (size 6)

An Upper East Side treasure. This original Valentino silver sequin mini dress was worn by Blair Waldorf (Leighton Meester) in Gossip Girl Season 4, Episode 3, “The Undergraduates,” during the Fashion’s Night Out party — one of the most iconic crossovers between the Gossip Girl universe and real New York fashion history.

The dress itself is a masterpiece of Valentino craft: a fluid silk base drenched in hand-applied silver sequins, cut in a wrap-style silhouette with a plunging V-neckline, flutter sleeves, and a cinched waist. The hem skims the thigh, giving it a playful balance against the structured sparkle — a look that was both radiant under the lights and distinctly Blair Waldorf’s version of modern glamour.

Fashion’s Night Out, the citywide event launched by Anna Wintour, was the fashion industry’s answer to global recession. Its cameo on Gossip Girl cemented the night as a cultural phenomenon. To see Blair Waldorf commanding the room in head-to-toe sequins wasn’t just a costume choice, it was a statement: fashion as theater, fashion as power.
