What to pack: Brooklyn
If it were a city in its own right, Brooklyn would be America’s third biggest. And probably its most diverse. Every language under the sun is spoken there and style-wise it roams all over the place, from the gaudy glitz of Coney Island to the mumblecore heartlands of Williamsburg and Dumbo. Despite this, there is still a connecting thread that runs through the borough, a kind of defiant not-Manhattan-ness, a studied insouciance, an irrepressible cool. To fit in when you’re there, you need to try really hard and give the impression at all times that you’re not trying at all.
