Sure you could just stop by the Columbia Bookstore with your ID in March or April (or even early May if you like living on the edge) to pick up your free cap and gown in time for Commencement.
Or you could start the collective celebration of your upcoming commencement by coming to

Stop by the James Room to pick up your cap and gown and celebrate with your classmates!
