About T-Shirt Design
Relax I'm Hilarious T-Shirt is pretty much made for someone who likes a good joke and does not need everything to be serious. Anyone who is into everyday humor will probably understand the idea right away.
It works for birthdays and holidays, but it is also the kind of shirt someone could wear whenever they feel like it. This is the kind of idea that works well on novelty shirts because you can understand it right away. It has enough personality to be funny without looking like it is begging for attention.
