My mum was visiting recently and was raving about this dress she saw advertised on Facebook. I reverse image searched it and I found some listings but from sites that I did not trust. I tried to explain to her the dress likely doesn't exist and show her dresses from brands I know of but she would just say "but it doesn't have ravens on" ????‍???? She's not even that into birds!

It's likely a longshot but does anyone know where I could get this dress legitimately or be able to recommend something that looks very similar?
