RARE JUNYA WATANABE COMME DE GARÇONS Embroidered Sweater Japan S

This is likely vintage but after much research, I cannot find this beautiful cardigan with embroidered flowers anywhere.I’m guessing at the original price. No material tags but it feels like a silk cotton blend.The faded tag says made in Japan It has some faint stains that I did not try to get out because I am not a fabric expert and did not want to try.The most noticeable one is at the collar. The others, mainly the arms are very faint.I’ve shown them in the photos. A couple of minor snags.And a split on the sleeve hem.This is still wearable as is and if you know what to do with this fabric, I would bet they will come out or at least fade.Please see photos for details and measurements.
