Bernd Hummel Holding, which acquired the Flop Flop brand of colorful thongs a couple of years ago, has appointed Uli Nölkensmeier as its new chief executive. The 37-year-old manager most recently ran the German sales subsidiary of Gas, the Italian jeans brand. He previously worked for Polo Ralph Lauren in sales, merchandising and customer service for the Germanic countries. He then switched to IT Holding to build up its Gianfranco Ferré brand in Germany and Austria.
