These 'Not My Type' shirts are a geeky (but adorable) way to proclaim your distaste of a forbidden font. The 'Arial is Not My Type' shirt, for example, is written in Helvetica. And the 'Comic Sans is Not My Type' shirt is written in DaveGibbons. Word nerdery at its best!
All 'Not My Type' shirts are made according to the principles of the Fair Wear Foundation, which supports fair trade practices for workers. To pick up a shirt of your own, see the links provided.
