There is no size tag. I am S and 1.68 m tall in the photo.
Approximate measurements:
Shoulder to shoulder: 45 cm
Armpit to armpit: 56 cm
Total length: 78 cm
There is no composition tag. Fabric feels like wool.
Very good condition. The white lining turned yellow on the armpit area.
Requires dry cleaning.
