I know my wife has a few skirts... none of them are wool, none have near the thickness, warmth, or remotely close to the amount of material in them that my kilt has.

I actually work with a guy who's wife makes skirts. A very heavy skirt for her uses almost one full yard of material. Neither one of them actually believes that my kilt is 8 yards. They think it's impossible. Which is also why they don't believe me when I say I'm usually colder in a pair of jeans.

So, this barmaid's comments are actually not very surprising at all, even if she wears skirts frequently...
