Finland is a little out of my range of experience, but my advice is not to wear it until you have a sporran and some hose and flashes to go with it. Then it might be more recognizable as a kilt to those not used to seeing them.
Porrick hails from Norway and maybe he can give some better advice for kilting in that part of the world.
But anyway, welcome to XMarks and I am looking forward to seeing how your xkilt comes out.
And one more thing. Don't worry about the laughing and pointing. I'll bet it will not be like you imagine. I was scared to death on my first kilted outing, and now it's no big deal. I've never had a bad comment yet. When I do, and I know I will someday, I will just ignore it and remember all the comliments that I have already gotten.
