Set to hit television, taxi cabs and online tomorrow, Fashion's Night Out is turning up the marketing heat with a star-, model- and designer-studded public service announcement.

Douglas Keeve, the director behind "Seamless" and "Unzipped," filmed the PSA which includes Sarah Jessica Parker, Diddy, Diane von Furstenberg, Ashley Olsen, Rachel Roy, Chanel Iman, Oscar de la Renta, Coco Rocha and Vera Wang, reports WWD.

While filming, each cast member was asked to wear the official Fashion's Night Out tee using his or her personal style.

"I was pleased to do it," Rachel Roy told the source, "I'm not an actress and I had to follow Sarah Jessica Parker, which was a little intimidating, but I had a lot of fun with it."

There will be several versions of the ads, including Coco Rocha and Oscar de la Renta (above) and look for Diddy dancing with Isaac Mizrahi.

In between prepping for her appearance on David Letterman, Anna Wintour stopped by as well.

Trey Laird, who developed the creative for the announcement, told WWD, "Anna showed up and she was cheering loudly, yelling louder than anyone else."
