I'm new to the community, so if this isn't the right forum for this question, I'd love it if folks could point me in the right direction.

This one's a bit complicated...

I'm a volunteer for a large, non-profit professional organization. One of my fellow kilt-wearers and I suggested that the organization should have its own tartan, so the kilt-wearing members could kilt up at our formal events and raise the organization's visibility by being seen in the tartan in public. We were blindsided by the board's primary concern about the proposal, though, which means it's something that's worth seriously considering:

Is wearing a kilt if you are not of Celtic extraction cultural appropriation?

My first reaction was to laugh, but those doing the appropriation never feel like they're doing anything inappropriate, so I thought it was important for me to get some actual input on the question (leading me to stop reading X Marks only in the public-facing side of things and actually register). Our organization has nothing to do with Scotland or Celtic heritage, except, of course, that many of our members are Scottish-American or Irish-American. So would it be inappropriate of us to register a tartan? (And the board isn't likely to be persuaded by "Bank of America did," because someone else doing something inappropriate does not make it appropriate.) Is encouraging our non-Scottish members to buy a kilt in the organization's tartan culturally appropriative behavior?

Our industry is particularly sensitized to this issue right now, so we want to be able to have a serious conversation about it. I'd especially love to hear from those of you who live in Scotland and Ireland. How do you feel when you see a random American with no connection to your country and your culture running around in a kilt? Does what tartan they're wearing affect that opinion?

Have any of the rest of you had this conversation before? (My Google Fu failed me for seeing if there's been a conversation about it in the public sphere previously.)

Thanks in advance!
