In making a tartan kilt great pains are taken to see that the pattern is centered, the pleats all match and/or maintain the intended pattern. When a pants leg has a seam on the outside the tartan design is disrupted. I was wondering if the same type of care was followed in making trews. Of all the trouser-type garments I have, even those with some design in the fabric, only the trews have no external seam. With as much pattern as you have in a tartan, it certainly makes it look better.
