There is plenty of Viking blood swilling around Scots veins. By all means wear the kilt and enjoy it. It might be worth you learning a wee bit about the history of the clan's tartan that you are wearing so that when an old "fuddy duddy" like me asks you the odd friendly question you can come up with an answer! We(I) do still assume, perhaps wrongly these days, that if you are wearing clan "A" tartan, then you are from clan "A"!!!! Have fun.
