I see no problem.

If there are set standards for something to be called a "Traditional Scottish Kilt" it doesn't mean that there can't be other types of kilts out there. But it would help give buyers a clue that if a kilt didn't have that label then it may not adhere to those standards.

As gilmore was noting this isn't an entirely new idea. Champagne and Cognac come from only certain regions in France. This doesn't mean that there are not some wonderful sparkiling wines and brandies to be enjoyed from elsewhere.

Cheers
