Advertisements for glasses that claim to "see through clothes" are almost universally . While the idea has existed as a novelty prank since the early 20th century, no commercially available consumer glasses can actually see through solid fabric to reveal skin in the way these ads suggest. The Reality of "X-Ray" Glasses
Some cameras, like the famous 1998 Sony Handycam with "NightShot" mode, could partially see through very thin synthetic fabrics (like some swimsuits or blouses) under specific daytime lighting. However, manufacturers quickly fixed this "glitch," and it was never integrated into a pair of glasses. Legitimate Related Technology

They typically feature a tiny feather or diffraction grating between layers of cardboard, which blurs the edges of objects and creates a double image. This gives the faint impression of seeing "bones" in your hand, but it does not work on clothing.
