Olivier Rousteing has been named the new designer of Balmain.

Following weeks of speculation, it has been confirmed the relatively-unknown fashionista will replace Christophe Decarnin at the label.

Olivier has worked at Balmain since 2009 in the Womenswear Design studio, and prior to that, he spent five years at Roberto Cavalli.

The French-born designer, who holds a degree from the Parisian fashion school ESMOD, is said not to be giving any interviews prior to the debut of his Spring/Summer 12 collection in Paris.

Rumours that there were problems at the French fashion house began last month, when designer Decarnin – who began working at the label in 2005 – did not attend the label’s Paris Fashion Week presentation.

His absence prompted speculation he had been admitted to a psychiatric ward, with Balmain representatives insisting he was just exhausted.

The reports were exaggerated, and the real reason he was not present seems to have been linked to his eventual departure earlier this month. Decarnin’s relationship with Balmain’s chairman and chief executive officer Alain Hivelin is said to have disintegrated, prompting the move. © Cover Media
