Defective Product

I have previously bought a lot of these shirts. Over time, a peculiar problem surfaced. Shrinkage (natural in a cotton shirt) affected one side of the front of the shirt, in the up and down direction, more than the other. As a result, the button holes in the placket increasingly became farther apart than the buttons, causing the shirt to have extensive wrinkling on the button side. I am not a tailor, but what I suspect happened is that the Banks buyers failed to specify how the warp and woof of the fabric were to be matched -- an expensive mistake.A second problems arises from product sizing. When I moved from a 16.5-34 to a 17-34, the shirt suddenly became a tent.I have not had these problems with other manufacturers, notably Eagle, Land's End and Enro.
