Vintage reversible tan and houndstooth jacket

This jacket has no tags, I believe it was handmade and tailored to whoever made it. It appears to be a quality vintage piece and is reversible.
It feels like it could be wool or wool blend, but there are no tags to indicate fabric make up.
I’d say it fits between a medium and large, but also looks cute as an oversized look on someone who wears smaller sizes than those.
