Mirroring the rejection of societal norms in Nirvana's music, the ripped-and-patched look of Cobain's clothes became the uniform of a generation.
Jacobs told The Telegraph in 2011 that the grunge show was his favourite, even though it got him fired from the label Perry Ellis.
"It was about... a dismissal of everything that one was told was beautiful, correct, glamorous, sexy," he said. "I think that moment hasn't passed. It's morphed into different things but it really hasn't passed."
Cobain might be horried to see the money now involved. Paris label Vetements recently issued a $1,150 version of the cardigan he wore at Nirvana's famous MTV Unplugged performance in 1993.
The real thing sold at auction in 2019 for $334,000.
Saint Laurent and Dries Van Noten have run versions of his favourite bug-eyed shades that have shown up on popstars including Jay-Z, Harry Styles, Migos.
But Cobain would no doubt welcome the way some of his fashion statements still reverberate.
An early critic of mysogyny and homophobia, he wore women's clothes on stage -- recently replicated by rappers (and avowed Nirvana fans) Kid Cudi and Post Malone.
For the cover of Rolling Stone, Cobain's T-shirt read "Corporate magazines still suck". He popularised the wearing of band tees, promoting outsider artists like Daniel Johnson (today, of course, the most popular is Nirvana's).
Then, when grunge took over the world, he couldn't resist subverting his own image, sporting a sparkly top by French designer Jean-Paul Gaultier in the video for 1993's "Heart-Shaped Box" and opting for suits, white shirts and ties in later performances and photo shoots.
It could have all devolved into parody. But by then, the pressure of being the icon of a generation was taking its toll.
"Cobain wanted to become a star but he was overtaken by the speed of it -- he intended it to be gradual, but that album (Nevermind) wasn't just successful, it defined a genre," said Dufaud.
Cobain died by suicide on April 5, 1994, aged 27.
