Sure, Serena van der Woodsen is supposed to be the talk of the town, but we’re more interested in Blair Waldorf’s prep-school style. This costume has all the naughty school girl appeal with a touch of Upper East Side class. An added bonus? Each piece is really cute and completely re-wearable! Get the deets, after the jump.

Don’t bother denying it, you’ve been trying to dress like Blair and Serena for months now. Well, your days of attempting to make $50 dresses look like Chanel are over, courtesy of Anna Sui. The quirky chic designer has just released images of her Gossip Girl-inspired collection for Target and we’re definitely getting the appropriate level of Blair vibes from the dress all the way on the left.  Check out the whole collection here before it launches September 13.

I love a hair bow as much as Blair Waldorf, but Lady GaGa’s (made from her own hair) is a bit much. [U.K., 1/15/2009]

Earlier this week, I let you in on how to be the Palin family for Halloween. Now, here’s the scoop on how to be two of pop culture’s most famous couples—Juno/Paulie Bleeker and Blair Waldorf/Chuck Bass. Yeah, we know, Chuck and Blair aren’t officially a couple, but they’ve gotten down and dirty in the past and their sexual chemistry is heating up this season. So after the jump, find costumes for these characters that you can totally re-use after Halloween. And remember, some of these items you can probably find in your own closet or your local thrift store, so spending a lot of money is unnecessary.

We have a love/hate relationship with Mean Girls. In reality, we know from firsthand experience that Mean Girls can ruin a teen’s life. But when it comes to TV and film, we find Mean Girls totally entertaining and have been known to root for them. Usually, the Mean Girl in a show or movie is the most developed character. Being saccharin sweet like Serena van der Woodsen in the first season of “Gossip Girl” or Lauren Conrad throughout the run of “The Hills” is easy. But it takes work to be conniving, cunning, and misunderstood all at once. We decided to pay homage to entertainment’s best Mean Girls after the jump. Tell us in the comments which one you identify with the most!

Celebrate the return of one of our favorite guilty pleasures: Gossip Girl, as well as, one of the season’s hottest trends: feathers. Rolled into one is this adorable headband from Jennifer Behr. (P.S. She makes all of the creations we see on Blair.) It’s a little pricey, but definitely a look we love. [$158, SaksFifthAvenue.com]

“If I were you, I would have rode me a little harder.”—Leighton Meester, aka Blair Waldorf, ad-libbing lines on the set of Gossip Girl. (This was the episode in which Blair finds out she’s not pregnant.)
