You can design a dress and have it made for you. People rate it and can even buy it from the site.

This idea would be a great business for fashion design as a whole. You could create a site that fashion designers can come test out their ideas. They post the design. A community votes on it and the top ideas get manufactured and sold. A cut is given to the designer and the website.

This would allow wannabe designers the chance to test the market place for the viability of their ideas.
