Vintage Authentic Randi Rahm Silk (?) Gown/Beaded Jacket Set

Beautiful beaded vintage set, no tags but feels and is most likely silk. In great condition with some loose threads which I have done my best to show in the photos. IMPORTANT: as my mannequin is a standard size 6 and the dress is probably more of a 10/12, she is wearing a cincher in the first couple of photos. Please use that to visualize how it should fit on the body it is meant for. Hem is asymmetrical, but measures roughly 50” long from top of strap, approx 16” across waist (under bust) and jacket roughly 15” shoulder to shoulder. Dress has zip closure, jacket has a hook/eye. Guaranteed authentic, sold as-is. Offers are welcome, trades are not.
