True Blair Waldorf enthusiasts know how important it is to stay ahead of the fashion curve, so when they heard there was a Pop-Up Shop set up at the corner of 54th and Crosby St. last night selling the "Gossip Girl" themed Anna Sui for Target collection three days before it hits stores, they were there in a New York minute.

As if scoring designer duds ala Blair, Serena, Vanessa and Jenny for under $150 wasn't enough to inspire text blasts of joy, the "Gossip Girl" cast was there to help celebrate in style. While I love everything in the collection, I have my eyes on the "Blair" dress worn by Emma Stone (above).

Check out this lookbook made up of Anna Sui's favorite celeb looks, and come back Monday for my exclusive interview with the famed American fashion designer.
