I spent a few hours yesterday visiting Harold's, Pockets, Polo, and a couple of department stores in Dallas just to see what is available in waistcoats.
The short answer is Nada.
I think I'm going to have Harold's tailor a waistcoat for me in herringbone with pants to match. What I'm looking for which is a high-waisted pant with a fish-tail back, an adjusting belt in the back, no belt loops, and buttons for braces on the outside of the waist. I want a 6/5 vest with 4 pockets and a notched collar to match the pants.
They can definitely make the vest. I'm waiting to hear regarding the pants.
This definitely allows for a proper fit since they can make adjustments at their shop in Dallas.
Here's a Country Sporting Suit that was offered on ebay UK. I don't believe I'll ever find one in my size but I may have one made.
The only change I'd make to this vest would be the addition of a notched lapel.
The only way I'll ever have pants like these will be to have them made. However, smaller gentlemen can still find them if they are patient and look high and low.

I like this jacket but I'd add a breast pocket on the left and change the pockets to patch pockets with an inverted pleat. I'd keep the flaps. I'd also add a throat latch.
I definitely like the double-vented back. I'd add a half belt and an inverted pleat to the center of the back above the belt.
That would be a suit!
I apologize for going somewhat
