Women's Vintage Denim Trenchcoat Jacket, Size Small/Medium

This is a beautiful and timelessly stylish jacket! It was my mother in law's, and my husband remembers her wearing it when he was little (70s- 80s). It's a very soft denim style fabric with silver hexagon buttons and accents. It was very well cared for and in great condition, except for a few small holes (see photos), possibly where buttons used to be? It's also fully lined. This coat has no size on it's label, but it is definitely a Small / Medium. There's no cleaning instructions, but I recommend dry clean or spot clean for care. I tried to google the brand, but couldn't find any information. I would keep this coat, but it's sadly not my size. I know someone out there will love this and give it the fabulous life it deserves!
