Future of Fashion - How can technology enhance and accelerate fashion start-ups and companies?

The Fashion sector is being transformed by technology. Mass customisation, bodyscanning, m-commerce, avatars, social shopping, digital stylists, and things we haven't even heard of are changing the face of the industry. Getting it right with innovative business models and unconventional marketing can make brands flourish (think UNIQLO) while getting it wrong with sleazy campaigns and a dysfunctional culture can make others sink (think American Apparel).
