Many of the tribes of the Eastern woodlands wore a kilt like garment. This was way before their exposure to Highlanders. However, this may be one of the reasons that the highlanders were so well received by tribes like the Iroquois. The other tribes that had contact with highlanders probably made good use of any kilts and plaids that became available at places like Ticonderoga and Bushy Run. I don't see why Native Americans would want a Tartan.
