David Koma has been appointed artistic director of Mugler.
The London-based designer, who replaces Nicola Formichetti, will start at the French fashion house in January.
He is expected to unveil his first collection for the brand in June and will make his catwalk debut in September during Paris Fashion Week.
"We want to write a new page for Mugler, putting it back on the map in the fashion business," Virginie Courtin-Clarins, director of development, marketing and communications told WWD.
"We have the potential to modernise it and I think the potential is huge."
Formichetti left Mugler in April after three years at the helm to join Diesel as artistic director.
Koma graduated from Central St Martins in 2009 before launching a successful eponymous womenswear line, which is stocked by 55 retailers worldwide. His designs are regularly worn by celebrities including Lady Gaga, Megan Fox and Beyoncé.
"We agreed that we wanted a real couturier," said Courtin-Clarins. "We feel we need to focus on the product, and that's why we're starting with the pre-collection."
