There’s no denying that the technology world is obsessed with fashion. Amazon, Apple and Google, three of the biggest names in tech, are all trying to carve their own path into the fashion space. Apple’s doing so with fancy smartwatches; Amazon with a shopping platform and voice-controlled cameras; and Google with conductive fabrics embedded in a smart jacket made by Levi’s. And the interest is mutual. Fashion designer Karl Lagerfeld, Chanel’s creative director, has expressed his love for tech by experimenting with partially 3D-printed pieces and runway shows that simulate a rocket launch. He’s not the only one either. Zac Posen, with help from fashion house Marchesa, worked with IBM’s Watson supercomputer to create a cognitive dress that lights up and changes colors based on activity on social media.
