Christian Dior Monsieur Vintage Men's Dark Grey Windowpane Pattern Blazer 45 R

Christian Dior Monsieur Vintage Men's Dark Grey Windowpane Pattern Blazer 45 R Vintage Christian Dior Blazer from the 70's or 80's? It's still in excellent condition EXCEPT inside the lining on the left side armpit area needs to be sewn. It's about $10 to have it fixed by any dry cleaner or seamstress. Please refer to all photos. There is no size number ( so it seems to be custom made ) in the blazer but from my measurements it's the closet to a "45 R" All my measurements are taken by hand with the item laying as flat as possible and are APPROXIMATE.
