Through the 1970s, paisley bandanas were worn by many blue collar and labor workers to keep dust out of their mouths and noses. The bandana's symbolism once again shifted in American minds, being associated with hard work. Famous country singer Willie Nelson began wearing bandanas when he moved from Nashville back to Austin, Texas "just in time to catch the hippie wave cresting at counterculture center the Armadillo World Headquarters." Around the same time, bandanas also became popular with motorcyclists, particularly with Harley Davidson riders and bikers." In the 1970s paisley bandanas also became popular amongst gangs in California, most notably with two well-known rival gangs, the Bloods who would wear red bandanas and the Crips who would wear blue bandanas.
