Of Scotland's many contributions to civilization (scotch, golf) tartan is right up there. And no Scottish ancestry required to wear it. The holiday season is traditionally the home of tartan, as it seems to provide a sartorial form of good cheer at any gathering. Pair jacket with the rest of your tux uniform, or let it stand alone with dark trousers and white shirt, even a turtleneck
||When choosing a tie, complement the green or black in this jacket versus echoing the red.
