XOXO, fashionistas! 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. The ensemble was styled with two eye-popping cocktail rings and '40s-perfect T-strap shoes.

For beauty, the new mom to baby James, whom she welcomed in December 2014 with husband Ryan Reynolds, modeled Old Hollywood-worthy curls, parted to one side. (Eventually, these were pinned up into a glam faux-bob hairstyle.) She also sported blushed cheeks and a pale pink lip.

The blonde bombshell took some time off from the movie scene after Gossip Girl wrapped in 2012. But since delivering James in December, Lively has returned to Hollywood, first premiering The Age of Adaline in April and now starring in Allen's latest, in which she plays the seemingly fabulous Kat. While there are limited plot details available, it has been reported that the film takes place in NYC's Chinatown neighborhood.
