Vintage 80s Diane Freis 100% Silk offset button down shirt / blouse

This is a gorgeous design from Diane Freis. It most likely had a skirt that went with it but sadly I do not have that 🙁 I am sure that was amazing too! It is 100% Silk. Made in Hong Kong. Dry Clean only. I do not see a size tag. It is meant to be loose and baggy. I am guessing it would fit a M/L. The back is about 2" longer than in the front. The bottom of the shirt curves up the sides. It is a button front blouse with the buttons offset towards the left side. There is elastic around the bottoms of the sleeves. It has shoulder pads. Shirt is in excellent condition. Measurements while shirt is laying flat -Across chest underarm to underarm -length from top of shoulder near neck to hem 31" in front and 33" in back
