The "Generation Gap", or the inevitable perceived divide in worldview between the old and young, was perhaps never greater than during the counterculture era. A large measure of the generational chasm of the 1960s and early 1970s was born of rapidly evolving fashion and hairstyle trends that were readily adopted by the young, but often misunderstood and ridiculed by the old. These included the wearing of very long hair by men, the wearing of natural or "Afro" hairstyles by black people, the donning of revealing clothing by women in public, and the mainstreaming of the psychedelic clothing and regalia of the short-lived hippie culture. Ultimately, practical and comfortable casual apparel, namely updated forms of T-shirts (often tie-dyed, or emblazoned with political or advertising statements), and Levi Strauss-branded blue denim jeans became the enduring uniform of the generation, as daily wearing of suits along with traditional Western dress codes declined in use. The fashion dominance of the counterculture effectively ended with the rise of the Disco and Punk Rock eras in the later 1970s, even as the global popularity of T-shirts, denim jeans, and casual clothing in general have continued to grow.
