About T-Shirt Design
The joke on Only Trust People Who Like Big Butts T-Shirt is easy to understand, and that is a big part of why it works. The everyday humor angle gives it a little extra personality without making the design too busy.
It works for holidays and birthdays, but it is also the kind of shirt someone could wear whenever they feel like it. The graphic tee style keeps the whole thing casual and easy to understand. It works well as a novelty t shirt because the joke is clear and the design has plenty of personality. It is an easy design to wear when you want something a little more fun than a plain shirt.
