Gossip Girl's Most Memorable Fashion Moments

Gossip Girl rule #1: While back-stabbing, scheming, and participating in general debauchery, one must always be dressed to the nines.

Ten years after the masterpiece show's premiere (yes, that's today—try not to feel old), Gossip Girl not only conjures up images of NSFW hook ups and heavy doses of teenage blackmail but also over-the-top fashun. From Blair's infamous headbands to Serena's high hemlines, Gossip Girl spawned many of our favorite '00s trends and helped many a private school girl reinvent her boring school uniform.

But when it comes to our very favorite GG looks, only two women can hold the title of Most Memorable. Obviously, I'm talking about Serena Van Der Woodsen (Blake Lively) and Blair Waldorf (Leighton Meester). Sorry, Little J, your handmade dresses showed promise but don't quite make the cut here.

Scroll down for S and B's best, most extravagant outfits that still inspire us.

After skipping out on Eleanor's photo shoot, and running off with the clothes that were supposed to be photographed, Blair and Serena looked chic AF in their own impromptu shoot near Central Park. And yes, this is the episode in which B and S pretty much invent the selfie.

Another giant neck flower FTW. Also, those black gloves—so good.

These debs wouldn't be caught dead in boring white dresses. Metallics only on the Upper East Side.

Blair's Cotillion Dress

No headband in this look, but the giant bow on her sleeve definitely makes up for it.

Serena's Studio 54 Party Dress

We want a remake of Gossip Girl but set in the '70s just so Serena can wear looks like this one all the time.

Serena and Blair's School Uniform

Cute cardigans (and headbands of course) are a great way to dress up a humdrum school uniform.

Serena's Thanksgiving Outfit

Thanksgiving on the Upper East Side is a time for friends, food, and high hemlines paired with fishnet tights.

Blair's Party Dress

From the look on Blair's face, and her phone in hand, we know she's about to do some serious scheming. Those sleeves contain her secrets.

Serena's Wedding Dress

Forever a lover of gold party dresses, Serena would get married in the eye-catching hue.
