I kind of get the idea,
....you have to deviate a little from tradition and make a few adjustments,
keep the traditional "Trachten-Jacket" in black, use plain black dress pants
or dress pants and add small "traditional" Embroidery around the pockets,
the vest can be traditional with an elegant print-design matching the ocassion, combined with a white dress shirt and instead of
your scarf or tie, use a plain or printed traditional Ascot, knotted Ascot
or ruche tie with a (bavarian) pin, where the color or print coordinates back to the vest!
Wear a black hat with an almost black "Gamsbart"!
Tell your tailor to use only metal buttons, color-gun metal!
In addition you could wear a silver or gold watch on a chain!
Best of luck!
