Tavi Gevinson is the ultimate cool girl. In 2008, the 11-year-old started the fashion blog Style Rookie. Three years later, she sported silver hair while chatting up Anna Wintour and Karl Lagerfeld at New York Fashion Week. Now she’s in charge of Rookie, an online magazine written primarily by teens, for teens, with only the hippest guest contributors (Rodarte, Thom Yorke, etc.). See what all the fuss is about at Rookie Magazine’s Yearbook 2 launch party, which is part of The New Yorker Festival. Music, ice cream, a reader talent show, and surprise special guests are promised. Want more Tavi? She’ll also be interviewed by the New Yorker’s Lizzie Widdicombe on Saturday.
