Balmain artistic director Olivier Rousteing has said robbers have made off with more than 50 pieces of the new collection that his Paris house intended to show at fashion week later this month. Posting overnight on Sunday on Instagram, Rousteing said a group of people hijacked his delivery driver on the way from an airport to Balmain’s Paris headquarters. He said they made off with the last pieces he had been expecting for the 27 September womenswear show – more than 50 items in all. He did not give a breakdown of the stolen items. “Our delivery was hijacked,” he wrote. “Thank God, the driver is safe. “So many people worked so hard to make this collection. We are redoing everything, but this is so so disrespectful. We won’t give up.” Rousteing did not specify which of Paris’s two main international airports the delivery was coming from. He wrote that he had been waiting in his office on Saturday morning when “our driver called us and said that he was hijacked by a group of people”. “This is so unfair. My team and I worked so hard,” he wrote. “We will work more, days and nights. Our suppliers will work days and night as well.”
