St John Red Santana Knit Zip Chain Jacket Cardigan Small Medium?

St John Red Santana Knit Zip Chain Jacket Cardigan Small Medium? Preowned. Has some flaws. No labels inside at all. It's the black label St john by Marie Gray when it had a label. There is another on here so you can compare. Hole in the back bottom and slight pull on left top see last 3 pics.. still beautiful and able to be worn. price reflects this. Armpit to Armpit measures 20 in Top of Shoulder to end 24 in So seems to fit small or medium. zip up closure with gold pull chain and made with a slit in the bottom middle under zipper.
