Fashion Week Spring 2009

"All of Julie’s clothes are so fun and sweet," said Gossip Girl's Leighton Meester, here with designer Julie Haus at her Spring 2009 fashion show. "It's all about this dress. I can wear it during the day and feel glamorous, then vamp it up a bit and it’s still sexy and summery for night." The actress had a busy day on Friday, hitting both the Jason Wu and Haus fashion shows, and then made a stylish appearance at Fashion Rocks.
