Why are you specifically looking for one that is extremely expensive? And if you're going to intentionally buy one that is extremely expensive, I would recommend getting a ticket to Scotland and getting one custom made. I knew someone who did that, and I'll have to admit, his kilt was by far the most authentic I'd ever seen (being handmade by a real Scottish tailor in Edinburgh and whatnot).
formal or casual?
It's just a plaid skirt, right? Go to a big women's shop.
