Sarah Jessica Parker made a subtle political — and fashion — statement while running around New York City yesterday in her Obama-inspired “Dare to Dream” tank. Her coveted tank is actually Zac Posen-designed and part of Barack Obama’s “Runway to Change” initiative. Posen isn’t the only designer to lend his talents to the campaign. Joining him in creating exclusive “Change” T-shirts, tanks and accessories are other top names like Nanette Lepore, Tory Burch, Russell Simmons, Vera Wang, Tracy Reese, Alexander Wang, Narciso Rodriguez, Beyonce and Tina Knowles for The House of Dereon and more. Your purchase of one of the Ts will count as a campaign contribution. Check out all the designs, at barackobama.com.
