Velvet blazer, no tags size 6

I bought this blazer at an estate sale, it has no tags or size in it. It is extremely heavy and well-made and I wish I knew what the brand was because it is gorgeous. Listing as a size 6 because that’s the size jacket I wear and this fits me perfectly, beautiful back, fully lined and just beautiful. I think this would be great for the holidays, with a simple pair of black jeans. This has the feel of a high-quality/luxury piece.
