Vintage 80s top in Silver Lamé, size small or 6

This size small (or size 6) vintage top (from the 80s) is made out of lamé, an expensive fabric. My research tells me that it sells in the hundreds (Isabel Marant or RHODE Mila sell tops similar to this for over $400). Unfortunately, there are no tags on this, but I know it’s vintage since I bought it over 20 years ago at a vintage store and it was already vintage when I bought it. It's a great dressy/costume piece with slightly puffy shoulders and cinches at the waist. One-of-a-kind.
