For some reason this pic reminded me of a particular scene in a novel I read years ago, Letters Back to Ancient China, in which a Chinese man from the distant past time travels to modern day Germany. If I remember right, he has tea or coffee with his neighbor or sth and she wears a silky semi see-through dress and he can kinda make out the outline of her crotch. It's been a few years, but I believe it's implied but never confirmed that she wears no panties in the scene. Kinda like in this pic.
