Look up 'kilt skirt' on ebay.

you will faint when you see what top=quality wool tartan skirts go for. I paid ten bucks for a flippin' gorgeous all=wool kilt skirt for the Invisible Joan in the dress blue stewart tartan. With shipping from florida plus the dry cleaning bill, she has a beautiful worsted wool kilt skirt for less than $30. It fits prfectly.

For a kilt of comparable quality I'd pay $300, even used...EASY. This thing is Gorgeous.....I *just* looked up 'kilt skirt" on ebay and I think I got something like 180 "hits". A few months ago I even thought about buying two skirts that were the same tartan, disassembling them, joining the halves and making a kilt out of the material. I swear the prices are LESS ...by an order of magnitude, what the material itself costs.

At prices like that, you can buy your lady one, she can try it out and if she doesn't like it, what are you out? Not much. If she loves it, then you know you can spring for a new one the clan tartan and it'll be fine.
