If I were going back to school in a few days, and I give thanks that I'm not, I'd pack two jackets first and foremost. One would be a safari of sturdy cotton drill, and the other a Norfolk, though not quite like the imitation version in the photo which lacks a proper set of pockets.
It's pockets you see that make both coats ideal for trudges to class. Particularly the Norfolk, whose built-in suspenders were intended to help support the weight of a morning's cartridges and work equally well for cell phone, iPod, and the day's assigned reading.
Like the safari jacket, the proper Norfolk has two buttoning pockets on the chest and two bellows pockets on the skirts that provide a considerable amount of storage. And the detail of bellows back and half belt adds a certain professorial air that might well be effective at attracting attention from young women who've been reading James Joyce.
Wear the Norfolk to class or the hardware store this fall with cordoroy or moleskin trousers and walking shoes. A turtleneck sweater is optional.
