I once had an Italian crepe suit. When I wore it, which was often, I pretended that I was Ingrid Bergman. This jacket reminds me so much of that suit.
It is black crepe ( 70%viscose - 30% polyester )with an amazing 100% cotton printed lining. The cropped style and fine , almost tuxedo, tailoring without closure make it a perfect dress jacket.
Although...as per everything in my closet I would also wear it with a tank and distressed jeans!
