There is no size tag. I am S and 1.68 m tall in the photo.
Approximate measurements:
Shoulder to shoulder: 39 cm
Armpit to armpit: 48 cm
Total length: 55 cm
There is no composition tag. Fabric feels like wool.
Very good condition. There are tiny signs of wear on the lining, some tears.
Requires dry cleaning.
