I'm usually not that into Dolce & Gabbana, but I found the Spring 2013 Menswear collection super neat.
The inspiration is Sicily, the hometown of Domenico Dolce. Sicily was exhibited in many different ways.
There was the fancy working dude, stripe-y beach vibes, and the prints of paintings that I could not find the source of. This was all done without getting too campy, which I bet is easy to end up doing, when attempting to capture the feeling of a place. According to the commentators in this Style.com video, it was very authentic. Placing the print on the sports coat was a nice touch, a reminder that this was not an exhibit on Sicily, but a fashion show.
Going back to the idea of creating an exhibition, age was an important factor in the show. The models seemed to span the ages of 11 through 52. (I geuss there's no age laws for modeling in Milan?) Apparently, many of the models were not models, but men and boys selected from villages throughout Sicily. This decision really made the show allude to the idea of the fashion of an island, rather than fashion inspired by the island.
