Vintage 1960s Style Rite Toronto floral cropped vest

Amazing unique piece! Authentic from the 60s. Some minor staining and discolouration on the inside (see last pics), but outside is in great shape. This vest was altered at some point to be smaller. You might be able to take it out again to make it bigger, but I do not know. No fabric tag, but feels like a cotton. Please check approx flat measurements below: Approx measurements: Pit-pit: approx 16” Shoulder-hem: approx 12.5” Across bottom: 14” Arm holes: approx 7” from shoulder to bottom of pit
