All dressed up with no place to go? (Gasp!) That just might be one of the scariest things to happen this Halloween. This is your one chance to be someone you’re not, so you better get your partially-exposed butt and painted face out there to a party. Looking to hook up, get high, dance like mad, or party like a sophisticate? Then check out our list of New York’s top Halloween parties in 2012. They all have in common one thing: OPEN BAR. So go! Drink! Flirt! Dance! And completely become that which you are not – for a night.
