Welcome, Gerhard, from the former New Amsterdam!

I would respond to your comment on District tartans by pointing out that using them, especially for ones outside of Scotland, would be like wearing a cap with the name of that region. It can either mark a resident or someone who wishes they were one!

I think that your wearing a kilt, regardless of the tartan, is the biggest barrier. Given that, your wearing the Holland tartan would be perfectly appropriate. Do you intend to wear your wooden shoes with it, though?

Btw, a photo of a kilt in that tartan would be appreciated.
