Hoodies

Back in the sixties they would have been occupying the VCs office if a Uni had tried to ban items of clothing. The design of some of Imperial's halls of residence have designed out the ease of occupation and riot (limited places to congregate, corridoors twist and turn etc).
If Imperial is anything like other Uni's then the staple fashion is the hoodie. Normally advertising a students course, year of study, hall of residence, or sports team! I could see several campus enterprises going bust.
And finally, when has a hoodie concealed a face? If it does, then how can the wearer see where they are going...
