What's the relationship between Kurt Cobain and grunge fashion?

Kurt Cobain was the lead singer and guitarist of the popular grunge band Nirvana, which emerged from the underground music scene in Seattle, Washington in the late 1980s and gained mainstream success in the early 1990s. Cobain was known for his distinctive fashion style, which was often characterized by grunge elements such as ripped and worn-out clothing, Converse sneakers, and beanies. He popularized the "grunge look," which became associated with the grunge music scene and influenced fashion trends of the time.
Cobain's fashion choices were often a reflection of his countercultural values and his rejection of mainstream norms. He often wore thrift store and secondhand clothing, which he modified and distressed to create a unique and rebellious look. He also favored comfortable, casual clothing that was easy to wear and move in, which helped to further establish the grunge aesthetic as a more laid-back and unpretentious alternative to the more polished and formal styles of mainstream fashion.
Cobain's influence on fashion extended beyond the grunge scene, as his signature style and the popularity of Nirvana contributed to the rise of alternative fashion in the 1990s. Many young people in the 1990s were drawn to the grunge look as a way to express their individuality and nonconformity, and the style became widely adopted as a symbol of youth culture and counterculture. Despite its origins in the underground music scene, the grunge look eventually became mainstream and was embraced by fashion designers and mainstream fashion media.
