Fashion's Night Out -- a global event organized by retailers and US and international editions of Vogue to celebrate fashion in hopes of boosting consumer confidence (and spending) -- is turning into one giant party!

As of the latest count, over 700 stores have signed on for the five-hour Sept. 10 shopping soirée.

Fashion insiders such as Patricia Field, Zac Posen, Roberto Cavalli and Christian Siriano are participating, as are Michelle Obama faves Jason Wu and Narciso Rodriguez.

Celebs and models are joining in on the shopping fun, too (making Manhattan skinnier than ever!).

Cindy Crawford -- fresh from her bare-faced photo shoot with Harper's Bazaar -- is slated to make an appearance, as is Gossip Girl Taylor Momsen.

Stephanie Seymour, Ciara and Miranda Kerr will all be taking part as well.

"Fashion's Night Out is that rare opportunity to meet the person behind the label," said Steven Kolb, CFDA's executive director.

With this beautiful (and stylish) of a crowd, prepare to dress to impress!
