Buying A kilt in Scotland. Any suggesd retailers?

[Mindrop]

So I recently had Testicular Cancer. I am now cancer free and am in the process of having a wish granted from Make-A-Wish. They are working on Finallizing a family trip to Scotland over spring break. I have Narrowed it down, out of the many things to do, to being in Edinburgh and Inverness. Can you guys recomend Kilt Shops in these areas? Also, what would I be looking at for prices. I would want to get more formal atire, like a Prince Charles jacket, possibly a fly plaid, etc. I would wear it to my cousin's wedding a few months later.

My family Name/Clan is Walker. I also have Macdougall in my family and I know historically, the Walker Family is asociated with the Macmillans.
