Radar Entertainment and The Last Magazine had an end-of-Fashion Week party to end all fashion week parties last night at the studio of Ross Kossovitz of K&M Tribeca, and we hear it was a rager--a "hot, sweaty mess" to be exact--according to David X Prutting, who snapped all the photos. Partygoers Alexander Wang, Stavros Niarchos, Richard Chai, Phillip Lim, Zoe Kravitz, Natasha Poly, Vladimir Restoin-Roitfeld, Byrdie Bell and a slew of others let loose into the wee hours.
