Tavi Gevinson is fifteen-year-old fashion blogger and a feminist who encourages everyone to embrace their complexity and look cool doing it. Tavi had a hard time finding strong female, teenage role models -- so she built a space where they could find each other. At TEDxTeen, she illustrates how the conversations on sites like Rookie, her wildly popular web magazine for and by teen girls, are putting a new, unapologetically uncertain and richly complex face on modern feminism.
