Kokosalaki, who has maintained her eponymous line since joining Diesel Black Gold in 2009, plans to vacate the Diesel role after showing the spring summer 2013 collection at New York Fashion Week.

‘The last three years I have spent at have been a very interesting and enjoyable experience,’ Kokosalaki said in a statement. ‘I would like to thank the whole DBG team for their hard work and support in helping me to establish this line. I am now looking forward to new challenges and wish Diesel Black Gold every success in the future.’

The brand has yet to announce a successor to Kokosalaki.

‘I am extremely grateful to Sophia for her work and the achievement of the growth of this line,’ Diesel founder Renzo Rosso said. ‘Thanks to her talent, Diesel Black Gold has defined its clear identity as a premium stand-alone label.’
