What is a canadian tuxedo?

A Canadian tuxedo is a colloquial term for an outfit consisting of a denim jacket or shirt paired with denim jeans. The term originated in the 1950s when Bing Crosby was not allowed to enter a fancy hotel in Vancouver, Canada because he was dressed entirely in denim. Since then, the term has been used to describe the fashion trend of wearing denim on denim. The Canadian tuxedo has evolved over time with different styles and cuts of denim being used for both the jacket and jeans. It has become a popular trend in recent years and can be seen on both men and women in casual settings.
