Argyll Jacket & waistcoat from 1900

[Tobus]

I have a waistcoat with pocket flaps as well and I really like the look compared to a more contemporary flapless pocket.

I concur on that point. I have two vintage waistcoats with lower flap pockets (one with antler buttons on the flaps, one with plain buttonless flaps). I prefer that look as well, and it makes one wonder if they were intended to be worn sans jacket. Yes, it has been said that the traditionalist stance is that a waistcoat should have a jacket over it, but why would they put decorative flaps with buttons that are clearly nonfunctional if they were never meant to be seen?

The close-ups of that tweed really show off the coarseness of the wool fibers. Given its age, I'm betting this was made from the now extinct breed (Blackface?).

The colour is very nice indeed! You wear it well. I would never live it down if I wore such a colour, given my university affiliation. Anything resembling burnt orange is a no-no for me.
