See gdl's comment about the two fits in the Noodle's thread. Short of it: if the Tipo works for you, then don't wait for the Lorenzo or equivalent cut. They are going to be very different (the latter will be drapier, lower gorge, wider lapels...or so I understand).
: what's the measurement on a 38/48 for the chest in the Tipo?
The lorenzo is definitely NOT drapier than the tipo. The lorenzo is actually narrower through the half waist (52cm on an eu50 as opposed to 53cm on the Tipo). That said, the shoulder expression is softer and slightly more extended with much rounder lines throughout.
