On another note, I found this academic article on Princeton and college fashion....
Plus, there is no reason that 25 inch bottom slacks couldn't slip over a pair of plus fours.
I agree. Baggy at the knees would be he best trousers, not at the bottom. It may well just be a matter of style changing, on the parts of top top down fashion designers or tailors, or bottom up, street fashion, or college fashion from rebellious kids, or as rebellious as an upper class oxford student can be.
Well, my college had a dress code which said no uniform but only formals. So most of the time I used to be there in formals usually in summer days and at the time of winter a coat over the body. It looked as if we are following some strict rules of jail or something. There was no relaxation even at the weekends.
I love my wardrobe
