UNKNOWN VINTAGE- LATE 70'S

So I do not have a lot of information on this shirt. I researched and could not find a copy. I am told it was bought in the late 70's. Amazingly, it looks brand new. I am sizing it Small- Med. Measurements are in pics. This is by far one of the most beautiful shirts I have seen. There is so much embroidery and the hemline is made up of the flowers. I don't think it has been worn. There is no fading. It's perfection!! PS- If anyone is familiar with the designer.....pleeeease message me! Thank you! ❤️❤️
