Personally, it's not a good match to my eye. Too many colors happening that don't go together.

Do you have a solid black kilt? Your white jacket is an idea I've toyed with for a while where you are basically just swapping out black tux pants for a black kilt with black hose. You could put some nickel or pewter buttons on the jacket and cuffs and maybe find some flashes to go with one of the colors in your hat.
