I'm not the authority that Matt is, not even close, but I will say that stillwater's wool kilts are hard to distinguish from at least the more casual scottish kilts. The fabric itself is very close to what I got from scottishkilts.net in a lochcarron tartan. Granted the cut and fit is superior to some degree in the Scottish kilt (though it's machine sewn also). There's loads of alternatives out there, and a handsewn tank is like the holy grail if you can afford it. It's definitely on the list for me, but until then I can make the cheaper varieties look pretty good and still get loads of compliments.
