There is perhaps no better way of passively broadcasting a political or social message than on a t-shirt. People cannot help but notice and read an eye-catching logo or writing on the t-shirt of a passer-by. Maybe as many as a thousand people in a day might absorb that logo or message into their mind, either consciously or subconsciously.

Wearing information that you believe in is also a great way of sparking conversation around the topic, and allows the wearer to expand on what is written or displayed on the t-shirt.

In essence, we are are all walking billboards, but the vast majority of us are blank adverts, or worse, walking promotions for multinationals and negative messaging. Make sure that your billboard is always promoting something that makes the world a better place in which to live.
