With more than a billion dollars from investors in 2012, there's no mistaking it: Fashion-tech startups are more than a fad. We meet some of the entrepreneurs working to give the fashion industry a digital upgrade.  Amanda Graber is the co-founder of Notorious, a fashion-advice startup that links users with stylists and what they call "fashion influencers." Rishi Prabhu is one of the founders of Bespoke Post, a lifestyle subscription service for men. We also meet Jose De Cabo, co-founder of Olapic, which aggregates user-generated photos for brands.
