Authentic Vintage 70s Psychedelic Blouse/Shirt

Dig the large lapels and the crazy orange print! I tried to find a Uni pic of me in this shirt in 1978 but alas the shirt has outlasted the photo. I loved this piece and the fact that I fit into it … then😝. Soft, brushed, stretchknit which I can only assume is a poly blend of something ? The print on the tag is plum worn away. It’s still in incredible condition with no issues. No pilling, holes etc. Listing as a small. Please go by measurements below. Pit to pit 18” Waist 16.5” Sleeve inseam 17”
