Vintage Rare The American Way With Wool Size Large Butter Yellow Jacket Coat

How much do we love this vintage coat? I don't see a size, but I'm guessing it is a large? It doesn't quite fit me. See pictures for measurements. It does have a loose button on the back sash and an extra thread on the top. Those are also in the pictures. Overall length from shoulder to hem is 41". Sleeve is 22 inches shoulder to hem. Shoulder to shoulder is 16" across.
