Vintage 60’s pale-blue beaded and sequin top

Gorgeous soft blue vintage 60’s evening top with crystal beads and sequins. Silk lined wool top. Back zipper with hook and eye closure. Marked as a medium. I would say that is true to size since I also wear a medium top. See measurements below. Approximate measurements taken with top laying flat. Armpit to armpit: 18.5” Shoulder to hem: 18.75” Hem across: 18”
