Jamie Keiles

In her blog/social experiment The Seventeen Magazine Project, 18-year-old Jamie Keiles set out to spend 30 days living her life according to the advice doled out in Seventeen magazine. She followed the beauty, fashion, diet and social advice, entered to win the freebies and posted the mag's photos of hot guys on her walls—then documented her reactions and results on the blog.
