JFS Signature leather jacket duster trench coat

This is a vintage black leather jacket, labeled a size medium. Please see photos for measurements of waist of jacket while buttoned up. The jacket is approximately 47 inches from the top of the shoulder to the bottom hem. No damage, scratches or knicks in leather and no damage to lining. All buttons are covered in leather and intact. Age of the jacket is unknown but I would guess that is 80s or 90s based on the style and shoulder pads. Non smoking household, but we do have one dog.
