Nope - thankfully, I've never seen a kilt in Burberry. Or Burberry in a Highland dress shop.
The tartans that anyone can wear are 'universal' tartans - most commonly Hunting Stewart or the Black Watch one traditionally; there are some modern universals too like the ones for the Scottish sports teams or Scottish parliaments. Most people are encouraged to choose from the district in which they live or have links to, if they're not entitled to a tartan by blood.
