Superstar fashion designer Karl Lagerfeld has died, aged 85, in Paris.
Lagerfeld also designed collections for his own brand and collaborated with high street brand H&M.
The designer had been unwell for several weeks, and had missed a number of fashion shows.
Many fashion industry heavyweights have paid tribute to Lagerfeld, including Italian designer Donatella Versace.
Designer Henry Holland also posted a tribute on social media, using one of Lagerfeld's own quotes.
Rumors had swirled about his health after he was absent from his Chanel show in late January due to what the company described as tiredness.
Lagerfeld, who transformed Chanel after taking the helm in 1983, was rarely seen without his dark glasses, a silver ponytail and fingerless gloves – gaining him the reputation as the most recognizable man in fashion.
The head of LVMH, which owns rival house Louis Vuitton, said the fashion world had "lost a great inspiration."
"We have lost a creative genius who helped to make Paris the fashion capital of the world, and Fendi one of the most innovative Italian houses. We owe him a great deal: his taste and talent were the most exceptional I have ever known," Bernard Arnault, the chairman and CEO of LVMH, said in a statement.
