Retailers all over the world are celebrating the fourth annual Fashion's Night Out (tonight Sept. 6, 2012) and Keeping Up with the Kardashians star Kourtney Kardashian is doing her part to help, promoting Dash's Fashion Night Out Event.

She tweets, "Dash LA's Fashion's Night Out event is tonight!"

Celebuzz reveals:

"The entire block on Melrose Ave. is participating, and there will be fashion trucks, food trucks, the works!

There will be a DJ, a ‘black carpet’ photo booth, and specialized “DASH-ing cocktails,” from Lola’s Martinis, plus seven designers are setting up pop-up booths featuring brand new fall merchandise.

There will also be some amazing swag-bag giveaways with donations from over 15 different designers."

It all starts at 7 pm in Los Angeles.
