Hence my suggestion for a lanyard.

Other issues to consider:
+ T-shirts get covered up on cold days
+ Jerseys can get too hot on warm days (esp long-sleeve jerseys)

Lanyards also allow us to wear our own TF clothes (or blasphemous(TM) non-TF clothes ) of choice, thus being less restrictive on people's fashion choice. I reckon you'd get better compliance with lanyards compared to shirts or jerseys. Not everyone might be willing to pay $23 for a T-shirt, but perhaps more people would pay a few dollars for a lanyard.
