This is a very interesting and playful design. It shows the skull with hair, wearing the crown. In many cultures, the skull is a symbol of death and mortality. Often its a very negative and dark symbol. But for the wearer, it can represent overcoming obstacles, and it can represent that the wearer has no fear of death.
The crown is a symbol of royalty and authority. It is a symbol of wealth and imperial blood. In this case, the crown is more like a “fools crown”, so the meaning can be sarcastic.
