Given that my surname is ultimately Flemish, and my mother's surname Dutch, I cannot simply wear 'my clan tartan' ... and I don't feel right wearing that of the mother of my children, who is Scottish on all sides, aside from a little MicMac a few generations back. So, as noted in other posts on other threads, I wear 'universal' or fashion' tartans exclusively - including the unofficial Canadian national tartan, the Maple Leaf, which is occasionally recognized by folk here. However, as noted in yet another thread, I will eventually wear a Macbeth tartan, while teaching a course on Shakespeare's play (and its sources and various adaptations), which will eventually get turned into a tank. And while I think I have some good reasons for wearing that tartan, I will still feel more than a bit weird about doing so.
