Most men on here advise against a tartan tie while wearing a tartan kilt and recommend a solid color or regimental striped tie. Also, most agree that Ghillie Brogues are rentel'ish. An Argyll jacket, solid color hose, Balmoral, traditional garter ties, and regular shoes sounds like it would work well. You probably have time to order some of the above mentioned iteams from the Scottish Tartans Museum(STM) if you want, I highly recommend them.
