Here is how this could effect someone in the US...

Your kilt, the one you made yourself, worked so hard on, would not be considered a Scottish kilt.

The kilt you ordered from Stillwater, USA Kilts, Freedom Kilts, Sportkilt, would not be considered a Scottish kilt.

The Kilt you had made by Barb, Matt, or another talented kilt maker, would not be considered a Scottish kilt.

While I agree there should be standards in place, I'm not sure I like the proposed definition of what should be a kilt. I agree that the artisans of Scotland should be able to protect the art they create in these kilts, I don't believe it should disqualify other quality kilts. It sounds good in theory, but I'm not quite sold on the idea anymore than I think French Champagne and Cognac is better than what is made elsewhere, or that Georgia sweet onions are better than Texas sweet onions.
