To the left is the cover of the official an EFY souvenir book from 1991. It consists of the title, Feeling Great, Doing Right, Hanging Tough, in 80′s-tastic font design, and a photo of an exuberant young woman doing a sort of cheerleaderish jump for joy [1]. What I noticed immediately when I saw this image was the presence of leggings. It was remarkable to me because I have recently observed some controversy in the LDS community surrounding leggings and modesty.
Now, I have to assume that whatever makes the cover of an EFY book is pretty much the definition of acceptable modesty in the church at the time the book was made.
