Took some thread research and here it is...
Posting from my phone, since my phone line (and internet) are royally screwed. What about things like tweed herringbone (surely appropriate)? Just my novice opinion, herringbone itself is normally okay. That jacket in particular is quite formal and suit like, compared to the others that have been linked to recently. I'm guessing it does come close to what you are saying, but is not in danger of crossing the line. Isn't it still perfectly good looking paired with any reasonably formal odd trou, etc? I can easily picture a Journeyman WIWT post with it.
