Welcome from Ohio.

You can certainly wear any tartan you like. I picked my two tartans, because I have a very strong respect for what they represent, and I wear them with pride. One of my kilts I have on order is in the Black Watch Ancient tartan and I am having that pleated to the strip, as the Black Watch is a regimental tartan. I will wear this kilt casually for my highland game competitions.

I purchased my other kilt from the Strathmore Woollen Company they are in Forfar Scotland, I do believe they are not to far from Edinburgh. I highly recommend them. My kilt was around $500.00

As for boots I wear Caterpillars with my kilts. They are extremely durable and just look great with kilts.
