This allows you more freedom in adjusting how tight the neck is. The most famous early wearer of the soon-to-be popular henley undershirt was the well-known actor, Wallace Beery. He wore the henley undershirt in so many movies, that the undershirt was called by his name. The henley became popular after GI’s started coming back from Vietnam with the military issued undershirt. The new adopters, having spent their early years hearing their parents call it the “Wallace Beery Shirt” continued with that name for a while. Eventually it reverted to just being called a henley, but for those in the know, it will always be a Wallace Beery shirt.
