Blake Lively Works Her Assets in the Most Serena van der Woodsen Way in Plunging Metallic Dress

Blake Lively was snapped looking stunning in a lamé dress on the set of Woody Allen’s upcoming, untitled film on Friday, Sept. 18.

But while the actress was clearly embodying her old-school character (the film is set in the ’40s), we think she was channeling someone else, too: her Gossip Girl character, Serena van der Woodsen.

Lively, 28, who stars opposite Kristen Stewart in the movie, worked her assets as only Serena could (and would!) in the plunging metallic number, which also boasted an open back. See the photos on Us Weekly
