Jil Sander silk blend jacket - EUR size 38 - Made in Italy

This lovely Jil Sander jacket is made of a silk blend on the outer shell and lining (see photo of tag) and is in excellent condition, with no stains or wear. It has a lovely sheen. Its tag says Size 38, but someone has written “40” on the tag - not sure why. It seems closest to a US size 6-8 or S/M, but please see measurements! Laying flat, it measures: Armpit to Armpit - 19” Top of Shoulder to Bottom = 23” Armpit to Cuff = 17”
