How to Launch a Fashion Tech Startup

I came from some engineering background to launch a fashion tech startup at a startup weekend, which again, isn't a normal thing. And it's always interesting to see where everyone comes from. So I was like, Oh, I just choose one of my ideas and see how it goes. And I purposely picked a name, which is Ninja Vest, because I didn't really care about the name. But from what I hear, you want simply Wall Street as well.
