Well, it sounds (from your group's website) as if your reenactments are done in good humor for the joy of those in attendance, rather than in an effort to achieve absolute historical accuracy, so it's not an issue that kilts weren't worn until well after the period of heavily armored knights. As a former SCA member (back when I was younger, thinner, and thought that getting bashed in the head with a rattan waster was fun), I applaud your work.

If you'd like a kilt that reflects the earliest documented style of tailored kilts, with high quality and excellent customer service, you might consider having Matt Newsome do a box pleated kilt for you. Matt's a forum member, but if you're not familiar with his work, you can see examples at www.newhousehighland.com .
