Same here. I take a 32 in the old Natalino sizing which is similar to the new 48 and Cavour trousers in 48 were way too tight. I’d probably size up to 50 or maybe 52 even next time and then have the legs let out and waist taken in.Hi! I have both and certainly 100% can say, that if you are happy with Natalino 48, Cavour Mod 2 48 will be tight. I had to return a pair of 48 size, despite the fact that my Natalino pair had to be taken in. I am considering sizing up, and also take a note that there is extra fabric along the inseam on Cavour trousers for letting out.
