stunning vintage women’s cape, style coat

This cape style vintage coat is absolutely stunning! It’s looks like Royal Stuart plaid, but I’m not an expert. It has no size markings but I am guessing medium. I am 5 foot one and can easily wear this with boots and I wear extra small, but this was my mothers jacket and she was a medium and was able to wear it with another coat underneath. The style is very forgiving and can fit a variety of sizes. The only flaw I saw it was on the pocket, please see the pictures for reference. Happy to answer any questions!
