This stylish and eye catching satin coat has no label, so It's really hard for me to say if it is from the 70s or 80s, but I think I am in the right ball park. Could it be hand made? Could be! The jacket is only lined across the back shoulder area. Three large buttons and a snap at the top, keep this closed, when the winds blow! The pockets are fake! Not much hem at the bottom, but the sleeves have 1. 5 inches hem to let down, if they are too short. Inside one armpit is a 2 inch near near the seam (see close up). The only other flaw is that the two lower satin buttons show a bit of wear, in the center.
Size is medium. Go by measurements:

chest: 42"
shoulder span: 16"
sleeve length: 21. 5"
total length: 27"
