as a person who has done Renaissance fairs for 20 + years and played a Scot at them for 15 of those. I have done historic research on the kilt. The first reports of the great kilt being worn starts about the mid 1500's. They were mostly the bed rolls being worn inted of rolled up and carried, or brats that were worn all the way around. I know that the mini ice age was in efect at this time as well. What gets me is when some one askes what tartan I'm wearing. For at this time there were no specific clan tartans.
