Vintage 70s Cocktail Dress Teal Blue

Vintage sleeveless cocktail dress with hidden zipper. Purchased from a boutique vintage store and worn only once for an event. It’s a hand-made dress (no label & the edges inside aren’t serged), maybe from the 60s-70s. Very lightweight material and feels like silk. Teal and brown pattern. Roughly a size 8. I can provide measurements if needed.
