I will closely monitor the performance of Viva's models at PFW, it would be at least strange that without an agency in Milan she is getting more shows than having a big agency and with strong names getting little/zero work. If Viva is losing strength in industry it can explain a lot, because at Dior show they had more than 70 models and only 4 were from Viva, if it is not that hypothesis in fact Viva doesn't care much about Doutzen, since her only major jobs in Paris aside from the shows were Vogue Paris, L'Oréal, Balmain and Mugler.
Maybe she left Women because of the percentage of the money they earned for her work?
