This is a rare find: a couture overcoat by Allesandro Manzani.

Made in Italy of 100% luxurious cashmere, it is black.

The coat has a button front, a center rear vent and flap front pockets. It is fully lined.

This coat is in PRISTINE, MINT condition. It looks and feels like it has never been worn. (There is a name embroidered on the lining. It could easily be removed or covered by a tailor.)

Marked 46R and meant to be worn over your size 46R suit or sport coat. 

It measures 22 inches from shoulder seam to shoulder seam, 26 inches armpit to armpit, 36/37 inches from mid-collar to the end of the cuff, and 48 inches from the collar seam to the bottom of the back. It has a 25-inch center vent. (All measurements done across the back with the coat laid flat). 

Please compare my measurements with a coat you have that fits you well.  You will NOT be disappointed.
