"The collective bargaining agreement sets forth a few very specific rules for how jerseys are to be worn. It says that your sleeves can't be cut or extend below the elbow. They can't be so baggy that the umpire can't see past them. Your jersey cannot "intentionally be untucked" and you cannot crop your jersey so that it cannot be tucked in. Most relevant to my question, though, is the rule: "Jerseys may not be unbuttoned below the bottom of the Club logo."
There is no reason given for this, so the only logical answer to assume is slut-shaming. Why couldn't a baseball player wear his jersey open to the world, proudly displaying a cute little cherry tattoo on his pec as his work uniform is unbuttoned to his surprisingly well groomed navel? What are they worried would happen? That ratings would increase?"
