I like the look of the shirt, I would probably have gotten one if it only had the Cerca Trova-words on it, but if a shirt is hinting that I do magic in any way at all, I don't want it. I think that's just going too far, and makes the art geeky.
I mean, let what you do speak for what you do, don't let your clothing speak for what you do. You want to give a good impression of what you do, and I think telling people in advance that you're a magician will give them time to get an opinion based on prejudices before you've even began performing.
