Last night's "Gossip Girl" was yet another ode to fashion.

The irrepressible Blair Waldorf, played by the gorgeous Leighton Meester, showed up to the opening night Halloween bash at Chuck's club in full-on flapper fashionista form.

She wore a blush beaded fringe Alberta Ferretti dress (from the designer's archives) with a '20s-inspired tulle-covered jewel and jet bead "St. Petersburg" necklace (below) by Suzanna Dai, $360; available on StarsAndInfiniteDarkness, long multi-stands of jet beads and half-gloves.

It's not too late for you to do the Roaring Twenties thing for Halloween.

Check out our below picks to pull off the perfect flapper girl -- a fringe dress, jet necklaces, chevron knit tights, Mary Janes and a tulle flower head band.

We also love the chic blush-hued cloche from J. Crew, which would have gone perfectly with Blair's like-colored dress.

And the best part about this costume is that you can get serious style mileage out of these chic pieces after Oct. 31. (Just don't wear them all at once!)

For added drama on the big night, top off your look with a feather boa and a long cigarette holder.

Oh, and you might want to practice your Charleston.
