Vintage grey Wesenjack wool jacket, L or oversized

This vintage sweater/jacket has super unique buttons and an almost-80s silhouette. The colour is blueish light grey, with dark grey trim. I'm a M/L and I think this jacket would look great as an oversized look on someone that is small or medium, or more fitted on someone L or XL. The arms are definitely long. It's super warm and would be great in late fall or early spring. The wool is in great condition although there is one discoloured patch, see pictures. Measurements: pit to pit - 20" sleeve (from top of shoulder seam) - 23" length (from shoulder seam) - 27.5"
