I mean, I guess you could wear it like a hipster or something -tongue-in-cheek/too cool for the school kind of way- but... I guess a very dark beige, gray, olive or black corduroy blazer may look quite chic as long as it is a fitted cut and very sleek in its pattern, but I cannot imagine it working for pants anymore. It is too robust and geeky.
Let me put it this way: the typical Dolce fitted blazer with two buttons and peak lapel may be done with black corduroy, and may look interesting. But I cannot imagine a typical old Brit man's square blazer working on anyone who cares about fashion - even a little.
The problem is; corduroy is soo thick, no one cuts a sleek design with it. It looks too bulky and square for today's clothing. Even blend wool suits are much lighter now that shows off an erect physique; nobody wants to get lost under that much of heavy and solid fabric.
