If you love vintage or bohemian style, try to look up: "Aoi Yu."
You would found a beautiful Japanese girl looking like this:
Her fashion fascinated many Japanese & Korean women.
This is one of my favorite Aoi's dress.
She have dreamy mood, and I just loves it.
If you like her style, you should focus on the "layer" and "vintage"
Most of her dresses are "Japanese vintage," which mean
that it would be difficult to find a dress looking similar to her's.
You could try to make your own, but the easiest way is to buy one from
Korean online shop called: "Sechuna."
They have similar style clothing to Aoi Yu.
Here are some picture of dresses that sechuna is selling:
