You are right on with the "old Hollywood" tradition. All I remember is being measured by Ken Sepetjan (? sp - one with the moustache) about 10 years ago, and he (and the process) was very straightforward. Sometimes an artisan maker can be very decided in his/her ways, and I don't remember Ken giving me that impression. He was very open to ideas. I wanted a band collar (we're all young once), and that was OK. I wanted a shorter width cuff to go along with the collar, and that was OK. They produced exactly what I asked for, in my measurements at the time.
Given the aesthetic of your Ercoles trousers I think you would have very good chemistry with them. Don't mind the Fioravanti effect, it's just marketing. The substance is there IMO.
The shirts themselves are not as "tightly made" as Kabbaz, more artisanally made than my Jon Greens, still top notch such that you'd probably pay more attention to how the details and fit turned out than construction. Interestingly, the shirts as I remember them wore "softer," in contrast to my Bassetti and NYC made shirts, which had a "constructed" feel about them.
Anto also has an amazing shirt cleaning service for all the shirts they make. I'd send all my bespoke shirts there if I could, but they only clean the shirts they make.
I think SF member Andre Yew here (a SoCal guy) uses them regularly and perhaps can help you more. Haven't seen him around these parts lately.
An example below (I worked with the gentleman on the right) - very nice looking shirt!
