An employee of mine is great at designing adult and non adult t-shirts. Here's an example of a T-shirt he designed to promote purefuck at the Vegas convention. This particular shirt was one of the most sought after T-shirts at the convention.
He's crisp and great at designing all sorts of promotional items. He's done some non adult shirts also. I remember his Fenway Legends collection was quite excellent.
