Was the collection all that Italian, and if so is it the Italian segment that Dolce and Gabbana typically leverages? Other than O Sole Mio blaring, the overall vibe seemed more Swiss-German-Austrian to me, or just ubiquitously European regal / opulent. If the collection theme is considered Italian, then it is of the more Alpine / Northern Italian variety and not the Sicilian / Mediterranean vibe that is typically associated with Dolce and Gabbana.
ETA:
Of course there were some looks that were built on the Sicilian / Mediterranean "chassis" like the corsetted body suits, but that is now a Dolce and Gabbana signature and variations of signature looks / silhouettes are to be expected.
