As an American whose entire genetic heritage comes from the cabbage / dill / sour cream side of Europe, kilts are not for me.
But rock on with your bad self, and don’t let anyone refer to that sporran as a purse.
If you ever wanted to kilt up, there are a lot of choices that do not track to any heritage. For example, I wear the Army tartan as a former service member. There are "just because" patterns that have no clan affiliation and you can rock on with your bad self if you wanted to. I have found out that Serial Kilting can be a lot like PAD and TAD.
