If you want folks to believe it's a "normal" ball cap, of course you'd wear it! That is how you prove it to be "normal" and beyond suspicion.
If I were to use the thing I'd have a stooge in the audience wearing it so I could borrow the hat as I moved into whatever routine it is I'd be doing. Psychologically this adds a tremendous amount of impact around whatever effect you do; it is they way Mentalists and Bizarrists have worked for more than a few generations (for the most part) in that "normal" (as in, it is something that is innocently present and used) completely takes away from our (the performer) randomly introducing an item such as his wallet or card case, etc.
Whenever I have a gaffed item like the Ball Cap or a Wallet, etc. I do my best to have someone I know and trust, to "lend it to me" during the act. I've likewise done reverse pick-pocket bits, loading one of my tools (such as a PK Pen) into a person's pocket... my whole objective is to create distance between me and the item I use. In the mind the public a borrowed item does not bring in reason for suspicion... then again, nothing creates suspicion more than "inspecting" something to prove it to be "innocent" or getting carried away with "making sure" something is impossible i.e. 100ft. of medical bandage + Duct Tape, Aluminum Foil and lead masks set about your entire head prior to driving a car down the road or locating a hidden something or other within the theater...
Simple! That's what works best. When it comes to this particular device (the Ball Cap) I love the idea but given today's outrageous sense of drama when it comes to the idea of possibly catching a germ of some kind... well, it's no longer practical... though there is room there, given said fanaticism, for a great bit of comedy... pull out a bottle of hand sanitizer, some towelettes and other such particulars whilst talking about being all so careful when touching other people's things (especially if you take the hat from a very well groomed chap)... its the kind of act that would make a very loud (and over due) social statement when it comes to how ridiculous we've become as a society.
