Olivier Rousteing has been named as the new designer of Balmain after Christophe Decarnin left the French fashion house. Rousteing, a relative unknown outside of fashion circles, worked at Roberto Cavalli in Milan for nearly six years and became the head of the Balmain womenswear studio in 2009.

He will make his debut this October during the Spring/Summer 2012 collection show in Paris.
