Who: Blake Lively
What: CinemaCon Awards 2011
Wear: Marchesa fall 2011 dress and Helena heels by Brian Atwood

Accepting the award for Breakthrough Performer of the Year, Blake Lively made a fiery-hot appearance at the CinemaCon Awards last night. For all her fashionable connections and chick-flick roots, you might think the Gossip Girl actress would look out of place next to her masculine Green Lantern co-stars. But cloaked in a red tulle, ruffle-skirted illusion dress by Marchesa, she showed off her stunt-toned muscles and looked every bit the stylish action hero. Add Brian Atwood’s towering ankle-strap pumps and this fashionista is ready to do serious damage to some comic-book baddies.
