So to get the tech vibe, start giving out free Goldman Sachs t-shirts and golden colored jeans to the techies. If you give it away for free, all the techies will start wearing them all the time.
I've wondered about that for signalling. Say for example there is a revered tech company in your city. Get their tshirt and people might assume you work there. Go to Meetup and more people may want to chat with you etc.
