God, don't you love a denim jacket? We are so far removed from it being actual workwear, and fashion has become casual to the point that restaurants have to beg men to wear polo shirts . But somehow a good denim jacket still retains an edge.
According to lore, the term "Canadian tuxedo" came about because of an instance where Bing Crosby was denied entrance to a hotel for wearing denim. (He had been hunting that day.) Elvis was actually known to avoid denim because it was still associated with being working class. It is—along with the chambray shirt—also the source of the term "blue collar."
I like to take the opposite approach to Elvis, more the Bing Crosby route, and lean into it. No one needs a story to wear a jacket, but I like to think about my grandad, a lifelong Louisiana farm
