Yoippari,

Your definition of "plaid" is incorrect. For a good explaination of the terms "plaid" and "tartan" read this thread:

I don't know of any flame resistant fabrics suitable for a kilt, but I do like my pv Casual from USA Kilts. I am no cloth expert but, in my opinion, PV does not look or feel like a synthetic material.
