Vintage Bead Fringed Off Shoulder Sweater, SO BEAUTIFUL!

This sweater no longer has a brand label or a fiber content label of any kind. I'm selling it for a friend of mine along with many other pieces I'm helping her with. I loved this one so much that she told me I could keep it, and I DID... but honestly, Arizona is just a little too warm to dress like this! I love it SO MUCH, and you will TOO!! It feels like your typical knit acrylic (maybe?) blend sweater, and the fringe beading is copper and multicolor peacock beads. It is worn off the shoulders. The pictures have to tell the story, because I don't have much to go on... it's just a really, really sweet little sweater! I believe it is vintage, but I don't know what decade. Maybe 90s. There is one area in front where it is missing a couple of strands of beads, but it really isn't that noticeable. It probably should be spot cleaned or hand washed to protect the beads. The size is really questionable... It's probably a medium, but I wear a large and I could make it work. It looks good on my size 6 mannequin, so it would probably be fine as a small too! I would honestly call it one size fits most!
