Didn't fit well, so unfortunately need to resell. From original posting:
Robert Geller zipper blazer from SS13. Black cotton fabric with a subtle herringbone pattern. Unlined. Double vent. Double zipper. All kinds of amazing.
Slightly wrinkled due to storage but those are easy to get rid of. Pockets are still sewn shut.
Fits kinda relaxed. Best for a 48, but a slim 50 might be able to pull it off.
Shoulder: 43 cm
Chest: 52 cm
