Fashion’s Night Out is arguably the biggest event held during New York Fashion Week to kick-off the week-long festivities. It’s when celebs pile into hundreds and hundreds of stores across the country (mainly in New York City) after hours, and pose for pictures, do press, hang out with their celebrity friends and do some late-night shopping.

Held last Thursday night (Sep 8), this year’s Fashion’s Night Out featured appearances from many celebrities, including Solange, Chanel Iman, Nicole Richie, Mary J. Blige, Rachel Roy, Amare Stoudemire, Angela Simmons, Dwyane Wade, Ne-Yo, Mary Kate & Ashley Olsen, and more!
