A school superintendent in New Jersey says a "misunderstanding" led an elementary school teacher to mandate that all students -- including young boys -- dress as women in a now-canceled fashion show to honor Women's History Month.

Maple Shade Township School Superintendent Michael Livengood said the show, which had been scheduled for Friday at Maude Wilkins Elementary School, has been canceled.

In a 16-page packet sent home with students, teacher Tonya Uibel alerted parents that all students in her third grade class would have to participate in the activity, since it would be graded as an "end of unit" assignment. The packet also included suggestions of how students may dress, including fashions from the 1950s, 1960s and 1970s like bellbottoms, poodle skirts and cheerleader outfits. Photographs of fashion icons like Twiggy and Madonna are also included.
