Just a simple question ( :3)

What's the type of coat that the females where when they are completely naked? Those long coats... yeah you know the ones.

I'm doing some hardcore searching for a specific hentai/manga that nobody knows the name of, so I'm putting matters into my own hands.
Buttttt.... If you want to help me with my quest on looking for this certain manga just click my name in the top left hand corner and go to topics and BOOM!! its literally the only topic there right under this one.

Thanks in advance ya'll \(^_^)/

Robes. Kimonos.
