When Gossip Girl first launched, Blake Lively launched to the front of fashion headlines, often ahead of co-star Leighton Meester.

However, Leighton has been stepping up her game lately and getting a lot more fashion attention. She looks lovely in lemon yellow at a recent event in Hollywood with costars Blake and Taylor Momsen (), and she ups the ante with some serious big-city style in this ensemble from Missoni.

She is jaw-droppingly stunning in this chocolate floor-length Valentino, showing us a very sophisticated uber-elegant side.

My favourite though may be this draped Missoni dress she wore recently. She pulls off this complicated outfit with effortless grace!
