The usual rule is professional athletes don’t bring their uniforms to set. There are some exceptions, like Joe Mauer, who insists on bringing his own catcher’s equipment as well. The other exception is when they shoot on the team’s home field, which is the case in this case for Prince Fielder and Chevy.
We did provide officially licensed, on-field authentic MLB uniforms for the players in the dugout behind Fielder.
Fun Fact: If you find yourself wondering why Fielder, a vegetarian, is singing about hot dogs, well, he’s no longer an herbivore. In a recent interview, Fielder professed that he had only been a vegetarian for about three months. Guess no one bothered asking him again.
