I recently purchased a Milano from a fellow SF'er. I wont say the price b/c it's beyond a steal and this will make you envious
I went to the E Zegna store in Beverly HIlls before sending payment to try it on. The fit of the suit "fits" me. As someone said, their arm holes are higher than the Roma and the the other (forgot the name) line. The waist is slimmer and overall its a slimmer fit than their mainline suits. I actually think its slimmer than their Couture's as well.
Overall, the Milano is such a beautiful suit that I'd buy more. Honestly, I'm a huge fan of E Zegna and cannot understand why other SF'ers arent. I highly recommend it but once again, you've to determine if it will fit you. Go to your local E Zegna store and try one on. Maybe this will help you. I'm 5'10 165 and I've very little body fat due to dieting and working out. My chest is about a 43 and my shoulders are . . . I think a 19 or 19 1/4. Waist is 32. I bought this in a 42R and it fits me to a T except I need to shorten the arms a little.
PM me if you've other questions.
