Vintage I Magnin beaded & sequined sweater

So stunning! Vintage (50's) beaded and sequined sweater from I. Magnin. Winter white/off white. Material label is gone, but believe it is cashmere/nylon. Lined, iridescent sequins with frosted white glass beads in a triangle pattern in front. 20.75" p2p, 20" length. Hook and eye closure, one hook missing (price reflects). Satin piping. Was dry cleaned last year, in storage after that. Great for holidays, parties, or any day you want to look like a million! xposted. Thank you for looking.
