A tech-savvy Italian fashion house has shown a prototype shirt with fibers of the shape-memory alloy nitinol interspersed in its fabric. Since nitinol returns to its previous shape when heated slightly, the shirt can be pressed with a hair dryer or even the body heat of wearing it. Even more extraordinarily, the fibers in the sleeves can be programmed to shorten when the temperature crosses a certain threshold, i.e. the shirt can roll its own sleeves up! Don’t expect to buy it any time soon; ‘the prototype shirt cost around £2500 to make, and is available in any colour you like – provided you have a tendency to wear metallic grey, that is. “But it looks distinctly bronze-coloured in some lights,” says (a company spokesperson).’ New Scientist
