Sudbury tuxedo

A plaid heavy shirt style jacket (AKA Lumberjack Shirt) worn by working folk in Northern places when it's too cold for just shirtsleeves, but too warm for a full coat (or it's mid winter, but you're just out for a smoke before rejoining the boys).

Kev's wearin' his best Sudbury Tuxedo tonight! Must be up fer some curling!
