Seeing a dress change color by itself is surreal, however, today's tech had made such thing to happen. Apparently, a London-based company that dressed superstars like Nicole Scherzinger and Katy Perry had created a wearable tech that alters its color. The smart dress will surely let fashion-geeks forget about the classic, little black dress.

The smart dress has a built-in sensor placed in its bodysuit layer. It works by sensing the breathing rate of the person who wears it. As inhaling and exhaling take place, the sensor begins to work that assists the graphene to change color respectively.

A shade of purple erupts as the wearer breathes rapidly, while it turns turquoise once the wearer breathes deeply. Meanwhile, it glows green when slow breathing takes place. According to Daily Mail, the smart dress, which had its debut at an event in Trafford Centre, Manchester is powered by a small battery.

"The thing that is amazing is that graphene can conduct electricity, but also be transparent," said the designer of the smart dress, Francesca Rosella. "This dress is a glimpse of what graphene can do, if you have a material that is transparent, can conduct electricity, is very lightweight and can be used as a sensor - you can create clothing for sportswear use and even everyday clothing, but with a hi-tech twist."

The structure of graphene cannot be easily seen by a naked eye, however, with the use of a microscope, shapes such as hexagon and diamond can be seen incorporated in the dress. The smart dress is made possible by the team of Richard Paxton, Trafford Centre's general manager with the help of the Cute Circuit company and the National Graphene institute at the University of Manchester.

For now, the smart dress that changes color by itself has no details about its price nor if it's for sale. Meanwhile, designers are optimistic about seeing the same technology to be used in inventing garments that can be set to display any design or hue.
