I’ve had two products on Betabrand, which is a fashion company in San Francisco that crowdsources its designs.  Ideas must pass through a voting phase followed by a crowdfunding phase before going into production.

I had disco leggings on sale for a time, and my disco trapper hat made it through voting but was only a few sales short in crowdfunding to make it to a production run.

While neither product is currently for sale, there is an instructable for the trapper hat if you would like to make one yourself.
