Since the bloody British were still in charge over here in '46 I would imagine the the Jacobite refugees refrained from wearing the kilt in public. However, I can vizualize a battlion of Jacobites in thier full highland garb with broad swords charging the British forces during the revolution. It would be interesting to know what exactly the custom was at that time regarding the wearing of the kilt, maybe someone knows.
