I've made kilts from the Rodeo and Super Target (yeah, I know) poly/cotton typically available at JoAnn Fabric stores. They don't always have both, or the color you want, but bug them and they'll eventually turn some up. About like Dockers p@nts fabric, probably just fine for Texas summer and maybe winter depending on where you are.

Black denim is also a good look, wrinkles some but easier to handle than canvas/duck. Wash it several times, too.
