Silky vintage top from 70s/80s

Beautiful vintage blouse in excellent condition. Please see photos for zipper at the back as well and the close up of the elegant floral design. Perfect to dress up with silk pants or skirt or dress down with black jeans and a leather jacket. The tag says size 8, but the pit to pit measurement (as seen in photo) is 18 inches so I listed it as a size medium to account for the difference between vintage and current sizing measurements. Selling because it no longer fits me 😭
