Rome looks very provincial imho, for a capital city it's especially sleepy and not vibing...
Might be, but it's largely irrelevant from a creative point of view, otherwise all designers based in London or NY should be brilliant - and they obviously aren't.
I agree with
@Lola701 that there can be something deeply nurturing in the sheer beauty of the place and also its slower pace can be an advantage for a creative mind (the role of Rome in the history of fashion has somewhat been obscured by the myth of Milan, but Valentino lived and worked there, with Capucci, Lancetti...kind of old school but greats nonetheless. And let's not forget Piccioli too).
Michele's aesthetic was inextricably linked to Rome's
genius loci, more than Giannini's, IMO. Also think of Dries, who has always chosen to stay away from the hubbub of Paris and kept living in Antwerp, a beautiful city but barely a cultural center...
I really don't understand what the protest of the Gucci employees is about at this point, the design studio has moved so many times already (Ford had it moved from Florence to London, then back to Florence with the interim, Rome with Giannini and Michele...).
On the other hand, I understand that moving again the studio to Milan might be based on operational reasons (closeness to manufacturers etc), but I hardly see any source of inspiration in Milan's drab Viale Mecenate, where the Gucci HQ are based.
