The Fashion Time Magazine reports that singer Rihanna wore a Zac Posen dress on the red carpet at the 2008 American Music Awards.

Zac Posen has launched Fashion the Vote, an initiative aimed at getting people to vote while also being fashionable. He wants you to take a picture of what you will be wearing on election day and submit it through the site.

"I am doing this because I want to make a difference, and I want to encourage people to get to the voting, vote for Obama, and have fun and look good doing it," Posen told WWD.
