Think of Threadless as “wikiwear”: a sartorial democracy in which people upload their own designs, have their work critiqued by Threadless' virtual community of artists and designers, and, if they’re lucky, see their work turned into actual clothing and accessories. After a decade of this groundbreaking design method, Threadless has built up a lifetime’s worth of eye-catching graphic print T-shirts, iPhone cases, wall decals and other items. Based in Chicago, Threadless makes its typically quirky tees in men’s, women’s and kids’ sizes, and also offers a small collection of shirts for pets. One of the fun aspects of wearing a Threadless shirt is that you just might walk past the person who came up with the idea in the first place.
