threadless

Threadless is a community based tee shirt company with an ongoing, open-call for tee design submissions. Not only are these some of the (in my opinion) wittiest, funniest, coolest t-shirts I've ever seen, a lot of them are proposed by regular customers of the company, not necessarily professional designers. Visitors to the site can also participate in the process by rating the design submissions before they get picked up for prints. You're also encouraged to send in photos of yourself wearing tees from the site, in exchange for credit towards your next purchase. All-in-all, it's one of the most community-oriented mainstream businesses I've ever come into contact with.
