The trick utilizes transparency to take advantage of the normally white background that images are placed upon. Under Danbooru's white background, for example, it appears like a SFW one-piece. Under a darker background, transparent areas shaped like ropes in the image can't hide among the white areas of the image.
For example, open this image in its own Chrome tab and add "background-color:black" to the body's style using the dev console. Instant shibari.

Dragging the image also destroys the illusion.
Hah, that would explain it; I've been using a white-on-black theme for ages.
