Salmo Dinner Jacket 

The regionally-famous SDJ is a plaid lumberjack shirt/jacket, named after the town of Salmo in the Kootenay region of British Columbia. While the SDJ is an archetypal 'Real Man's Jacket' and a classic piece of working man's attire (hence the Poor Man's Tuxedo theme), the term is intended to be an ironic mockumentary of the town of Salmo, (and indeed any equivalent 'no frills' town in North America) which is basic in the extreme. Salmo has also been referred to as an 'X-Files Town'...
