The balthazar is 1cm shorter in the body with a slightly narrower, bellied lapel and a two button closure. Its basically the Isaia Gregory and it existed well before I started. I made the tipo longer with a better lapel but it just didn't sell at full retail. I fought with every store about it for two years and finally gave in. The tenero has the same lapel as the tipo - its just 1 cm shorter, unlined with a completely soft shoulder. I think its the most versatile model we make.
I would think theses changes are minor to the general public (and maybe even buyers). You mean to say a Bloomingdales shopper looking for a suit would pass up an Eidos model based on 1cm length, shape of a lapel, and the third button? I would think these are apparent and more relevant to a more informed crowd like those on SF. This a result of looking at the data/sales numbers?
