I guess this is kinda cool, a dress – at least the front side of one – composed of “scales” that can change from mirror-chrome to dull metallic on command. But even though it’s made of individual scales, it does not appear to be terribly flexible, and seems likely to be uncomfortable.
Still, if it could do more than just “shiny/matte,” but actually change colors, it seems like it might have a future. Specifically… plate *actual* steel scales with this material and make practical lamellar armor that can change color. That seems like it might be an interesting fashion for the future as society continues to get “enriched.” Shiny, perhaps even golden, armor when you’re out and about, and at the flick of a switch it turns matte black when the time comes to throw down.
Sure, here it seems to be pitched at the female market. But I suggest culturally appropriating the tech and making it the Must Have Man Product of the 2030’s.
