Serena's First Season 5 Look

She might be appearing in big action flicks now but Blake Lively was back on set for Gossip Girl Season 5 on July 19.

Dressed as Serena, Blake swept the streets of New York in a floaty Rag & Bone skirt which was paired with a Matthew Williamson beaded vest, plain white top, and load of gorgeous M.C.L. arm candy.

The Rag & Bone "Feather" Skirt costs $395 at rag-bone.com.
