Thank you for your message and interest in the Benjamin Sartorial suits. All the suits feature higher armholes and a slimmer Italian fit. They are all fully canvassed and are fairly classic. The Granoro, Classico, and Classico II are all basically the same block difference. It started with the Granoro and then we made some extremely slight adjustments which most people wouldn't even notice (adjusted the collar positioning slightly) for the Classico and Classico II. These are all discontinued (no longer produced).
The Nobile is a new model, again with high armohles and fully canvassed, but the shoulders are slightly softer than the Granoro/Classico and the fit is just a little bit more form fitting than the Granoro/Classico - particularly in the shoulders. Also the lapels are just slightly larger (9 cm vs. 8.5 cm of the Classico).
Please note that while still classic and conservative in style, the Benjamin line is cut a little bit slimmer than most American commercial/mainstream brands.
I hope this helps.
All the best,
