She started a style blog at age 11 that quickly became a must-read for fashionistas everywhere. At age 13, she was invited to New York Fashion Week as a special guest and sat in many a front row. At age 15, she launched Rookie, a smart, respected feminist website for teens that drew more than one million page views in its first five days of going live. What can teen phenom Tavi Gevinson do to top her many successes?

The blogger/editor/writer can now add acting to her resume! Gevinson, now 17, hit the Fox Searchlight party at the Toronto International Film Festival on Sept. 7 in support of her new film, Enough Said, looking gorgeous and all grown-up in a long-sleeved black and red dress by Wren. Her hair, which has been dyed nearly every color from flaming red to geriatric-chic gray, was styled into a stylish blonde bob. In her acting debut, she stars opposite Julia Louis-Dreyfus and the late James Gandolfini as the best friend of Louis-Dreyfus' movie daughter.

Gevinson, who's currently applying to colleges (Brown, Wesleyan and Barnard are high on her list), recently spoke to the Daily Beast about her new movie and what it's like to have been working so hard for so long.

"People are like, 'Did you miss out on childhood?' My childhood lasted a little longer, because that was at an age where all of my friends were having 'humping parties' -- which is a thing when you’re 13 -- and I came home every day from school, got dressed up, and took pictures and edited them, and made mood boards and collages and checked out magazines," Gevinson said. "It felt very pure at the time."
