Dark blue velvet vintage rug top

This is a VERY funky vintage piece that I got in Spain. It’s dark blue and velvet so it’s super soft. I love it to death but the 1 button does not close at the top for me (right below the rug-looking fringe). Good condition still! It doesn’t say what size it is but I’m guessing it’s a small because I’m usually an M and in between the buttons exposes some of my skin.
