Cameron Russell (a model) recently gave a TED Talk in which she explains the power of images - both in person, and in the media.

'Russell strolls onstage in a short, form-fitting black dress looking every bit the professional model who has represented brands like Victoria’s Secret, Ralph Lauren and Chanel and appeared in many an international edition of Vogue. But then she does something radical. She puts on an outfit far closer to what she would normally wear — a wrap skirt and flats. Her point: “I was able to transform what you think of me in 6 seconds,” she says. “How we look — though it is superficial and immutable — has a huge impact on our lives.”' - via TED Talks blog
