Only one team in professional sports has an appearance policy worthy of its own Wikipedia page.
For almost five decades, the Yankees have hewn closely to late former owner George Steinbrenner's attitude toward facial hair. New York's players are expressly prohibited from growing "any facial hair other than mustaches (except for religious reasons)."
The policy has long polarized opinion among both Yankees fans and baseball fans in general. Some argue its persistence into the 21st century keeps New York unique, while others deplore its restriction on players' individuality.
