I've been looking at pictures in the Harvard archives, and it looks like back vents and flapped (but jetted) pockets) seem to have been *preppy* norms for a long time.
Really? Â I have never looked at said archives, so this is news to me. Â By back vent, do you mean center vent? All of the Apparel Arts
drawings that I have seen show dinner jackets with no pocket flaps. Â Similarly, the old Esquire
captions throw cold water on center vents. Â For my money, those are about the two most authoritative sources that exist. Besides, Harvard kids were known for flagrant violations and outrageous get-ups, like highland plaid dinner jackets and evening shirts with button-down collars. Â You wouldn't countenence that, would you?
