I understand that the Hudson Bay Company is responsible for the proliferation of the "Canadian Tuxedo". The Canadian Tuxedo is described as a denim jacket with jeans. The denim jacket must have patches on it to fully qualify. However, I can't place a date on when this was done.
The wool shortage I refer to is mentioned in this Chicago Tribune article. I understand this must have caused a change in consumer fashion and I have to imagine that it would have meant that making clothes out of cotton would be a suitable alternative. However, I don't know if the wool shortage was that bad in that it would have made such longer lasting fashion trends.
Anyone have any firm dates on when the Canadian Tuxedo emerged and whether these two events are linked?
