You seem awfully worried about getting in trouble for wearing a certain tartan. Relax, very few people will even know what tartan you are wearing. Just know what a tartan represents if you wear it and wear it with honor and pride.
As others have said, I wouldn't worry about it too much. While at the 2005 Stone Mountain Highland Games, a vendor from Glasgow enquired about my Blackwatch kilt. He didn't recognize the tartan, nor did he seem to understand it's significance when I told him what it was.
