Dove conducted a social experiment to prove that women are more beautiful than they think, as part of its continuing focus on "real" beauty in its advertising.
In a campaign by Ogilvy Brazil, filmed by John X Carey of Paranoid in a San Francisco loft, the beauty brand employed FBI-trained forensic sketch artist Gil Zamora, who usually sketches people described by crime eyewitnesses.
First he drew portraits of women according to their own description, and then he drew portraits of those same women according to strangers who had met them on the day. The differences between how they describe themselves and how others describe them are immediately striking.
(UPDATE: The inevitable parody has arrived -- now using a sketch artist to test guys' self-image.)
