Just three months ago we announced that Kazakh socialite and oil billionaire Goga Ashkenazi had acquired a majority stake in Vionnet. Now, the design duo have announced an ‘interruption’ in their collaboration with the Parisian brand, according to a report from WWD.

Sources in Milan told the paper that the London-based Ashkenazi had ‘clashed with the designers.’

Barbara (who previously worked with Prada and Gucci) and Lucia (who cut her teeth at Valentino) were hired just last October by former owners Matteo Marzotto and Gianni Castiglioni, who remain as shareholders of the label. The twin sisters succeeded Rodolfo Paglialunga, who also had a brief two-year stint at the label.

Despite the turbulence, the house will stage its first full-scale runway show since 1939 on the 28th of September, marking its 100th anniversary—albeit designed by an in-house team.
