Yes, I would like to know the same thing - especially because it is accepted as correct in the following sentence: "Sei il mio migliore amico". Any thoughts or comments on this, anyone?
I don't know if this is correct, but I think I remember seeing a comment stating that syntax when it comes to adjectives is less important in Italian, and you can change the position to indicate meaning. I don't know how true this is though.
I just realized your comment is 2 years old, but I'll reply anyway.
