Grail! Capsule piece! Vintage Christian dior. "The suit" made in USA.

any clue what year this could be from? great subtle contrast on thick navy pin stripes. beautiful burgundy silky lining. 100% worsted wool made in USA such a unique design. note visible top button. the rest stay tucked away. New York city paris vintage high fashion throwback couture I'd have to guess this has to be very hard to find, esp in this condition! size is women's 12 but would look great on a smaller fashionista as a over sized piece.
