jrafter, I feel burgundy adelaides are best with navy suits or jackets (mostly in heavier clloths, due to their brogueing). Otherwise they're pretty distracting, despite their loveliness. Have you tried that suit with any calfskin captoe kicks in a chestnut (or lighter) brown?
Glen plaid flannel suits are your friend - the pants can always be used (in grey or even brown) as odd trousers blue blazers.
For any other odd jacket, that's beyond my expertise & I usually go for solid flannel trousers.
