The event was full-on energy from the start, with free runners using the show set for a parkour performance to kick off the show.
The audience was wawing foam boxing gloves and wearing tanks for Team Wang and Team H&M.
The fashion show which was also streamed live on hm.com saw among the guests Jessica Chastain, Mary J. Blige and Dakota Fanning.
The show also saw hip hop artist Sharaya J and Missy Elliott perform live on stage, while afterwards Dj Diplo kept the party going into the night.
"Tonight's event for the launch of the Alexander Wang X H&M collection was about high energy and a full experience that goes beyond fashion, from the attitude and speed of the show, to the pop-up store in a locker room setting, and the performance by Missy Elliott and Sharaya J at the after party" says Alexander Wang.
"Tonight's celebration truly reflected the theme of the Alexander Wang X H&M collection. It was like being at the ultimate meeting between fashion and sport and it was perfect to launch in New York." says Margareta van den Bosch H&M creative advisor.
I am so excited I will be able to preview the collection next week so I will report on my favourite pieces!
The collection will be available in 250 H&M stores worldwide from November 6th 2014.
