Meanwhile downtown Alexander Wang hosted his after party at the Emigrant Savings Bank complete with bank robber theme—bank tellers became bartenders. Prabal Gurung hosted a karaoke fete to celebrate his latest collection at The Standard East Village. Gurung may be one of the hottest designers around but the man also has some serious skills on the microphone.
