ZARA faux leather Jacket

This leather jacket was gifted to me a few years ago. I never really wore it because it was very boxy and unflattering on me. The only damage is a tear in the interior on the armpit seam of the lining, but the exterior and rest of the jacket is pristine and has no damages. Also, I’m regularly a size Large and My Sister is. Size M, we both have broad ish shoulders and can feel a bit tight in the armpits and shoulder area.
