The humble promotional t-shirt is pretty much a default item in promotional campaigns these days. It would be incredibly hard to find another form of advertising, which not only provides large advertising space, but also walks as a walking billboard, for literally a fraction of the price of an actual billboard. We have always said the main importance when buying a t-shirt for promotional purposes is make sure you get the branding correct, attractive branding is what works the best, and this does not necessarily mean a screen printed 10 colour design, a simple 1 colour print can be just as effective.
