>>1521719I asked Grok and got this:
The trick behind the optical illusion where an attractive naked lady appears when zoomed out, but is actually just a guy’s armpit up close, relies on clever positioning and the brain’s tendency to interpret ambiguous shapes based on context. In this type of photo, the image is staged so that the contours of the armpit—typically the curve where the arm meets the torso, along with some hair or shadow—mimic the silhouette of a woman’s body when viewed from a distance. Zoomed in, the details (skin texture, hair, folds) clearly reveal it’s an armpit, but zooming out blurs those specifics, letting the overall shape suggest a human figure, often with the armpit hair doubling as the “head” or “hair” of the illusory woman.
The illusion works because our perception flips between two scales: up close, we see the literal reality (an armpit), but from afar, our brain fills in gaps and assumes a more familiar form (a person). It’s a play on pareidolia—where we see patterns like faces or bodies in random objects—combined with deliberate framing. The humor comes from the surprise of realizing the mundane truth after expecting something more provocative. These kinds of illusions often circulate online because they’re simple to create—just a well-angled photo—and they exploit how easily our eyes can be fooled.

But the links cited don’t seem to include the illusion in question.
