Gorgeous vintage St. John Evening by Marie Gray black and crème sweater size 12

Vintage St. John short sleeve sweater with subtle sequence just enough to catch the light and sparkle! From my assessment all sequence is in tact. Sweater has back zipper. Is a mock turtleneck. Does not scream sequence or after 5 in my opinion. I would wear this to the office during the winter months or even late fall.No fabric tag I can find but feel like a heavy cotton blend maybe with a touch of wool. Classic, timeless sweater! Size 12. Please see all photos. Thank you!
