Part of the hooplah of Fashion's Night Out included the unveiling of some fabulous Fashion Week-themed displays at the W Hotel in Union Square.

This was not only to celebrate Fashion Week, but a collaboration between W Hotels and Barneys stores. Through October, W guests in cities where there are Barneys locations will receive exclusive perks like complimentary bellinis and discounts when they shop at Barneys New York and Barneys Co Op stores.

Simon Doonan, Creative Director of Barneys New York and Eva Ziegler, Global Brand Leader W Hotels Worldwide (pictured together, above) were on hand to provide commentary.

I asked Doonan about why Barneys wanted to team up with W. "Well, this is a very happy collaboration because Barneys and the W Hotels are very compatible in their outlook -- because they believe in style, they believe in humor, they believe in a little bit of hedonism," he replied. "We both like to take that "New York sizzle' and take it on the road."

Zielger later added that W wanted to "show the outside world our passion for fashion."

Check out the festivities below -- including celeb appearances and Doonan's tips for having a great Fashion Week!
