A man’s proper suit of clothes was worn by gentlemen, bankers, clerks, professionals… virtually every man except those who labored manually (such as miners). Given men owned so few items of clothing, they certainly wore what they had, despite the demand. Levi Strauss developed the original “Levi’s 201’s” and “Levi’s 501’s”, built to last in the clothing-destroying mines. Compare and contrast the “suit of clothes” with Levi’s originals.
In Victorian men’s fashion, Collars and Cuffs were something altogether separate and different than a shirt. A whole different paradigm, given today’s men’s dress shirts are one solid piece, with the collar and cuffs attached. See vintage images of the styles and reasons why tailors (and factory producers) bothered to make the collars separate–and why some were made of PAPER rather than fabric.
