Both of my kilts (tanks) fit like a glove. Both kilts were purchase at a local shoppe, the first was the from the Celtic Craft Centre is San Francisco in 2000 and I just received my second from the Highland Scottish Gift Shoppe here is Calgary.

I have the copies of the sheets of paper that had my measurements written on them. The only difference in the measurements was 0.5" at the waist and 2" at the hips. My first kilt was measured tighter at the hips, but the allowance for sitting was made when the kilt was made. My first kilt fits me perfect on the smallest setting; I had to convince them that I wasn't going to get any larger as I got older (I'm very slim) and that my size wasn't going to change.

My latest kilt fits at the just-smaller-than-the-middle setting so I have room to shrink or grow. I doubt either will happen.

The nice thing about having these two sets of measurements and having them be so close is that I will feel more comfortable ordering a kilt online, which will save me some $$$ if I ever go for kilt number 3.

Measuring is definitely important. Ask your kiltmaker how s/he likes measurements taken. I got two different hip measurements, but both kilts fit the same.
