Looks like Blake Lively's having as much fun with fashion as her stylish alter-ego on Gossip Girl, Serena van der Woodsen.

Chanel's newest face attended WonderCon 2011 in California wearing a fashion-forward dress from Carven's spring 2011 collection. The blue and black dress features cap-sleeves and a puff-ball skirt, and Lively added a white bustier top to the ensemble. She gave her outfit a pop of colour with red ankle-strap Louboutin shoes and bright red lipstick.

What do you think of the star's puffball-and-bustier dress? Is this look hot or not?
