neck

I am from boston, and going to exit tomorrow night with some friends. wondering what time draper usually comes on, what time the club actually closes about, and if there is a dresscode. can you wear warmups or sleeveless shirts into the club?? i know inside the club everyone has tang tops on, and some with shirts off,,,but can you get in with a sleeveless shirt or tang top. and are sneakers allowed... thanks in advance:D
