Threadless
Think of Threadless as “wikiwear”—a sartorial democracy in which people upload their own T-shirt designs, have them critiqued by Threadless' virtual community of artists and designers, and, if they’re lucky, see their work turned into actual product. After a decade of this groundbreaking design method, Threadless has built up a lifetime’s worth of eye-catching slogans and designs. And who knows—wearing one of these, maybe you’ll walk past the person who came up with the idea in the first place.
