Over the course of the years, I've learned [that] fashion is a fascinating business about selling magic. It is done on the backs of our optimism and our insecurity. It is as much psychology as commerce. But I've also learned that every day we make split second decisions about people based on their attire and those decisions can have powerful implications - see the story of Trayvon Martin and his hoodie. It's important for us to understand how fashion works and how we connect to it.
