It's been awhile since we last heard the famous phrase, "You know you love me. XOXO, Gossip Girl [1]," — and we've been on a downward sartorial spiral ever since. Though fashion-centric hits like Pretty Little Liars [2] and Scandal [3] have delivered their fair share of inspirational moments, we've yet find a small-screen fashion phenomenon quite like Gossip Girl.

Iconic style moments dominated the Upper East Side, but it was Blair Waldorf, played by the stunning Leighton Meester [4], who was always one step ahead of the style pack. She was a classic beauty with a royally bold disposition [5], and her polished style translated into the masterful portrayal that captured the hearts of tastemakers around the globe. From the launch of cult-like trends — one word: headbands — to the crème de la crème of designer duds, it was Queen Bee who reigned supreme.

We're summoning 37 spirited style tips from the one and only Mrs. Blair Waldorf-Bass.
