Paper crane tunic or mini dress from anthropology

In the last photo you can see that if it were a little looser in my bust area it would hang more flowy but it's a little tight because I wear a 36b. I should have got a medium instead of a small and it would've fit as it should. I think it would be perfect on someone who wears a extra-small/small, because it's meant to be a little over size and that adds to the beauty of this dress. It is also lined.
