Now me personally. I have enjoyed pleated trousers for many years now. During my transitional period from suedehead to punk, I enjoyed a brief period wearing outrageous electric blue and red pleated baggies from a certain shop in the kings road, chelsea. Even after the punk thing died out, I returned to pleated trousers as opposed to anything bondaged or zipped, and had a pair of trousers made in tribute to mr. bowie at the carnaby cavern. they were burgundy and had twenty pleats (I still have them). Five each side at the front and five each side at the back. They would make a good wind sock.
In the following years post 1970 - 85 I have pretty much settled on pleated trousers, although a much more tamed down version more akin to those worn in the states. However, with the big Mod revival over here in the UK most suits and trousers have reverted to flat fronts. It has taken a year or so for me to accept this and start wearing these (or a single pleat with some of my work suits).
What is the Ivy League take on trousers pleated or otherwise, and bear in mind I am of the fuller figure so skinny trousers are a total no no? If they must be flat front then the have to be wide fitting not drainpipes.
