It always easy to know when the cast of ‘Gossip Girl’ are in between takes because they’re wearing flip-flops.

Leighton Meester was spotted on set last week in a store in New York City wearing a Valentino Pre-Fall 2010 dress.

Her silver sequin dress has a plunging neckline and a twisted detail at the waist.

The neckline has been opened to show off her beautiful necklace.

It’s the perfect look for Leighton’s character Blair. I’m just dying to know what shoes will be paired with this look.

If you’re hoping that Blair and Chuck get back together, you’ll be happy to know that Leighton does too.
