I like the Benetton campaign a lot and in spite of and maybe even because of its repetitiveness. I can't tell that these models are not professionals, and I am not sure if they truly are non-professionals or perhaps mostly model wannabes who are not signed to a major agency. From my vantage point and taste, these folks are gorgeous and have camera presence and this looks far better than most other multi-model campaigns, most notably the multi-model campaigns by top photographer Mario Testino for top label D&G with "real" models.
I don't give a rat's patoot that "real" models were not used since the system under which "real" models are discovered and developed only has to do with talent and "it" factor within the narrow confines of what the agencies think that the likes of Miuccia Prada, Riccardo Tisci and Carine Roitfeld find appealing.
