From SoHo to Harlem and in more than 500 U.S. cities, Fashion's Night Out (FNO 2012) is making its return this year on Sept. 6 with more than 4,500 events nationwide.

Fashion's finest, including designers, editors, models and celebrities like Kim Kardashian and Nicole Ritchie, will rub elbows -- and shopping bags -- for a night for the annual shopping extravaganza.

The definitive guide was released on the official Fashion's Night Out website Monday, listing the full schedule of participating stores around the globe. The event runs from 6 to 11 p.m. Sept. 6.

This year marks the fourth year of Fashion's Night Out, kicking off the first official day of Mercedes-Benz Fashion Week in New York. The first fashionable fete, spearheaded by Vogue, the Council of Fashion Designers of America (CFDA), New York City and NYC & Company to boost sales during the recession, began in 2009 in just 300 stores around the city.

According to the website, "Fashion's Night Out is an unprecedented global initiative created in 2009 to celebrate fashion, restore consumer confidence, boost the industry's economy during the recession, and put the fun back in shopping!"

Last year, Fashion's Night Out extended to 18 countries. The events will feature sales and deals for shopping, entertainment, freebies and refreshments in most locations.

Participating retailers will have the official collection of 2012 Fashion's Night Out Merchandise for sale, with T-shirts and bags starting at $25, some of which will be donated to an AIDS charity.

Others on hand will include Alessandra Ambrosio at Victoria's Secret, Whitney Port at What Goes Around Comes Around, Rachel Zoe and Thakoon Panichgul at Bergdorf Goodman and Solange Knowles at Diane von Furstenberg.

Cirque du Soleil will perform at Henri Bendel as well as free food from some of New York's famed food trucks and cocktails from The Mulberry Project.
