For wash and wear ease from working to casual dress-up a Utilikilt Mocker might fit your bill better than the Workman or Survival. It's made of poly-cotton, side-slash and rear-welt pockets. I've had one and I've never had to iron it - shake right from the dryer and put it on. No wrinkles to speak of. You might also consider the Stillwater Kilts Nightstalker standard. It's more of a traditionally styled kilt than a UK, washable, and very little need to iron. It's an acrylic fabric.
