My wife paid for her grad school entirely by selling direct-from-manufacturer fashion goods, from China, to middle-aged upper/middle-class women in central Europe. The crazy thing that made it all work, IMO, was that the website was invite only. The women used the exclusivity as a status in their social circles, and invites as favors. It's fascinating how these small market niches exist but it really is the other 95% that makes them take off.
