Funky XS retro trench coat - light blue/dark blue stitching and buttons

Groovy light blue trenchcoat with dark blue stitching and buttons. Circa 1984 – when I went to college. Worn maybe once. Left sleeve snag from where outside tag was. See photo. Small iron spot? On the back - probably will be covered by belt and not noticeable. Last photo is of inside lining which is perfect. 31 inches from shoulder
