You jest but I tend to think it'd be much better for posture and breathing if pants with more flexibility and wiggle room were in fashion for men. E.g. sweatpants. I had a teacher at uni who wore those and I thought he looked rather funny, but in retrospect I can empathize.

Some companies make "dress sweatpants", e.g.

but I never bought any because even in promotional pictures they still tend to look too much like sweatpants.
