This is nothing to cheer about.
According to the New York Times, Washington Redskins cheerleaders were required to pose topless for a calendar shoot in 2013 while in Costa Rica.
From NYT:
"A contingent of sponsors and FedExField suite holders -- all men -- were granted up-close access to the photo shoots. ... One evening, at the end of a 14-hour day that included posing and dance practices, the squad's director told nine of the 36 cheerleaders that their work was not done. They had a special assignment for the night. Some of the male sponsors had picked them to be personal escorts at a nightclub.
