Blair, Serena, and even Chuck became style icons, influencing high school trends everywhere. Girls who identified themselves as Blairs rocked headbands and tights, while the self-proclaimed Serenas preferred boho-chic pieces.

“Retailers, designers and trend consultants say Gossip Girl … has one of the biggest influences on how young women spend money,” reported the 2008 New York Times Influence on Retail.

And even high-end designers like Chanel wanted to be part of the crowd.

“Everyone wanted to be there,” Daman told the fashionista. “Because there were so many paparazzi and the girls were constantly being shot in the street with their Chanel bags or their Fendi bags or their Chloé boots, which gave them editorial attention, everyone jumped on the bandwagon.”
