Vintage Barbie size asian style dress can't find it anywhere please help does anyone know about this dress fits barbie perfect

This is a vintage barbie size dress in very good condition, fits midge perfect
however I have done hours of research looking for this item, I don't believe it to be handmade the stitching, the way it fits, the material it just seems
better than handmade, I searched rare japanese exclusives. I've seen similar but not this one. I would love for anyone who might know something please
let me know. I have just said forget it that it must be nothing and going to
just add it to a vintage clothing lot, but something inside of me tells me no
not until I know. we have something here called the goodwill bins, which means the trucks get the donations, and then empty them in great big bins
and goes out to the public to dig through, so basically from the street to the trucks and then the bins and sold by the pound. It's really great you never no what you might find.
thank you for your time and hopefully your knowledge
