For a SC, I think windowpane can work very well on a rough textured green or brown tweed. This is due to the casualness of the earthy colors.
But due to the combination of the vertical lines and navy color, a blue windowpane SC will draw the association of a suit. Something about the navy color + lines just communicates "suit" to me.
It's like a wide pinstripe with horizontal lines added. Looks very "banker" (navy pinstripe)
