Say what you will about his shifting design sensibility, Alexander Wang sure knows how to throw a rager (so much so that at times the collection seems to be an excuse for the main event). This year the Wang phenomenon seemed to reach critical mass: massive company growth, ubiquity, a new store, the season’s most star-studded front row, and a total circus at the show.

Clearly, this called for an after-party of epic proportions, and epic he delivered. Taking over a parking lot on 17th St and 10th Ave, under the High Line, Wang gave his fans a carnival, complete with rides, booths, games, and, of course, unlimited booze. Perhaps this was also a wink to the carnival-like atmosphere that has developed around the once-cult, now-mainstream label.

The line to get in wrapped around the block, as party hopefuls begged for precious wrist bands with protests, pouts and tears. Those lucky enough to score one were treated to the best county fair this side of Jersey, including a carousel, bumper cars, inflatable trampoline, and firing-range games. The choice prize? A Belvedere Vodka stuffed bear.

Obviously, this wasn’t going to be a stiff fashion affair, but a good old-fashioned bash, and attendees took this credo to heart, putting on their best moves on the dance floor in front of the stage. Revelers included all the front row, model besties Iris Strubegger, Agyness Deyn, Erin Wasson, Ryan McGinley, Terry Richardson, Russell Simmons and Chris Brown, who’s been everywhere at the shows.

The evening’s big rumor had it that MIA would be perform, and if on cue the diminutive rapper popped up, with the Wang entourage in tow, and bum-rushed the stage. Caught in the surge, we ended up backstage, where—and you won’t believe this—MIA looked at us, winked and said, “Do you love to dance? I do!” And with that, she proceeded to bust a move of hip-hop classics. We had no choice but to follow her lead. At one point backstage, we did overhear someone go onstage (little Baltimore rapper Rye Rye), but by now the party had kicked into high-gear and we were just along for the ride.
