Sixties long dress with slip flower and beautifull

It is from kindles of California. It's from the sixties which is getting awfully popular again. I took pictures of the slip and dress.it is a gorgeous orange the dress has big 3 quarter sleeves and will go to your feet depending on how tall you are. It says one size fits all. I don't believe anyone ever wore it. My aunt always sent my grandmother hats and clothing which my grandmother always kept but never wore. It won't let me put one size fits all on the bottom so I hope you read this. Sorry..
