Another great option is to make your own. I know only the very basics of a sewing machine and had no trouble putting an X-Kilt together. My wife even asked where I bought it - and not condescendingly Adding rings and pockets and such not that complicated either. I did some practice tests and will on my next one. Also contemplating snaps or straps/buckles. Really, just imagination the key after the basics are done.
