Menswear business Berwin & Berwin is taking on the contract to manage Baumler in the UK from January 1.
The stake had belonged to previous agent Jason Gerrard, whose Geko Fashion Marketing represented Baumler for 25 years. He and Berwin rescued the business from administration in November 2009.
Kate Berwin will manage the brand from the start of next year.
The brand starts 2013 strongly, with House of Fraser opening six concessions for spring and planning a further 10 for the autumn.
Berwin said: “Baumler is a fantastic brand and the suits are crafted in a truly original way. I think the brand will thrive here in the UK and will show a new level of quality for men’s formalwear”
