Beautiful, vintage, jacket with zipper

This is super cute and I wish it fit me! Tag has been faded away but it has little zipper and cute front pockets. I love the white contrast ditching! I'd say this jacket would fit a small or even cozy/oversize on an extra small? Please feel free to reach out with any questions. This garment is an overall good condition for its age, but it is old and may show some minor signs of wear.
