Let's wait and see the debut collection?
We should go back to the comments of the last few shows of Donatella and her teams work and ask when was the last time we or our friends, family members bought a bag, knitwear, tailoring, a shirt even from Versace.
These potential candidates are just being contacted by headhunters, interviewing for a job. They were professionals employed by their previous employers/creative directors to executive, implement and contribute to their vision, who knows maybe Dario loves 90's D&G, Gianni dresses and Helmut Newton, maybe not.
Look at Nico de Felice for example, doing a fantastic job at Courreges which had zero resources when he arrived, he built a small atelier, improved the fabrics, lowered the price for knits and the patent carry over pieces for what is already contemporary pricing, trained under Ghesquiere's strict schooling, came from Vuitton which is flamboyant in its own sense, decorative and completely the opposite of what he is doing at Courreges - he shares just the same standard of construction, dedication and thinking as the school of Ghesquiere/Natacha Ramsay, and he is completely executing his own beliefs and taste.
People who say they want e.g. Galliano at the helm of half the brands out there, John at one period was so stressed out in his 2/3rd year the Menswear team worked on 1 single collection over 2 years because he couldn't make any decisions and too stressed to show anything. Talented at draping and creating a theatrical image? 100% yes but how many owners want to pay 2 years worth of development and 1 million euros per year on a menswear team salary alone for 1 show in 2 years.
