There you go; get a dress oxford shirt in a complimentary color, a solid tie and you're good (my setup is green hose (primary color of kilt) red flashes & tie (color of primary stripe) light blue dress shirt, brown brogues, belt, & sporran, stag antler sgian). This is a very comfortable hot-weather rig; cooler to me than a Jacobite shirt, and much more presentable.
