Gorgeous Vintage Psychedelic Dress 1970s

Bright and beautiful vintage slip/nightie that I've worn as a dress. It's unbranded and in good vintage condition (believe it's from the 70s due to its construction). Very Barbie! The top is lined (photo 6). The hem has come unrolled (photo 5) , but it wouldn't be that much work to tack it back up. No pit discolouration!
