What I can and can't wear?

[MacSimoin]

Heath,

Have a look at MATTHEW NEWSOME'S PATENTED ADVICE FOR THE FIRST TIME KILT WEARER. I think he does a great job of explaining the ins and outs of kilt wearing in this article and as an answer to your concerns Matt states:

Most people choose to wear a tartan that has some connection with their heritage. But the choice of which tartan to wear is entirely personal. There are no "requirements" to wear a tartan, no "authorizations" needed. You simply pick the tartan you want to wear, whatever your reason.

I agree.
