Cohn made his mark by adorning Western-cut suits with galaxies of rhinestones, forests of fringe and symphonies of sparkling oversize G clefs. He fitted Elvis in gold lamé; created a shocking ensemble for Gram Parsons, the proto-country rocker, embellished with pills and marijuana leaves; designed hundreds of shirts for the singing cowboy, Roy Rogers; and parked a star-studded 10-gallon hat on Elton John.

People romanticize cowboys for the same reason they romanticize gangster rap. It is the idea that there exist somewhere men for whom masculinity is natural, not a performance. The biggest lie of course, in rap and also Westerns, is that anyone exists who can kill people and have no feelings about it. That is how countries get men to join the army and go to war, by glamorizing this idea, and why they then get PTSD (shellshock) and are fucked up about it for the rest of their lives.
