Vintage 50’s style strapless light blue/teal slightly iridescent chiffon dress

This is a beautiful strapless chiffon 50’s style strapless prom/party dress. I’m told it is dated between 1974-1995. Total Mermaid vibes! Union made. It has lovely detailing around the bodice. Ribbon straps have been added and are easily removable. This is in good vintage condition. The zipper is still in good condition! Approximate flat measurements- Bust- 33” Waist- 24 Hips- 36” Some average signs of age like slight pulling at bodice and some slight fraying as seen in pictures.
