Well, yes, my Casual Model has been called the "Dockers" of kilts. 1" pleat reveal, with a pair of side slash pockets, a pair of rear welt pockets and an under-apron pocket is about the closest you can get to slacks. That is if you can get around the idea that "Dockers" fabric is a solid color, Poly/Cotton.

The problem is making a machine washable kilt in the Armstrong Tartan. I have checked my sources and it seems that Tartan is only available in Wool. That means dry clean or hand wash.

And I'm afraid that a custom made kilt, by anyone, is outside the price range you seem to be looking at. That leaves you with a mass produced kilt made from an Acrylic fabric. No pockets. And in some other Tartan.

Good luck in your search.
