The prom was also free, but under one stipulation: Teens were required to sign a pact agreeing to dress and behave modestly, to dance "appropriately" and to abstain from using alcohol or drugs.
"This prom is unique in that it emphasizes wholesome conduct and dress," said Marcia Stornetta, director of public affairs for the Utah-based Church of Jesus Christ of Latter-day Saints in Morristown.
But, she insists, it's not at the expense of fun.
"There is no pressure to do anything immodest or reckless, like party or drink afterwards," said Anna Jensen, a junior at Ramsey High who attended the dance. "The music was clean and the dancing was also clean. Overall, it was just a group of kids, Mormon or not Mormon, that wanted to enjoy themselves without being influenced by what our modern society believes to be the norm."
The nearly 300 students abandoned several conventional prom practices including arriving in limousines and wearing expensive outfits. (Organizers encourage attendees to be modest in their spending as well.) Most were dropped off by their parents, and some of the girls swapped or borrowed dresses to keep down the cost.
Because some of the students came from long distances (students from New York and Connecticut have attended in the past) and were driven to the event, there was a "parents room," where adults could socialize during the prom.
Some students attend the Mormon Prom in lieu of their high school prom, while others, such as Anna, go to both.
"They are both equally fun, but the standards for Mormon Prom are different than school prom," Anna said. "The standards that are given to the youth such as dancing without intimate contact, and listening to clean music, are all things that I choose to follow because they help keep me safe, as well as help me to enjoy the dance more without being distracted by things that really should not be the focus."
Anna, who is Mormon, brought two Catholic friends to the dance.
Another Mormon, Matt Norton, 16, is a junior at Morristown High.
"I'm going to my school prom in May," he said. "The types of dancing and music will be very different. It will be more inappropriate at the school prom."
His takeaway from Saturday's experience? "Girls still look good in modest dresses."
The Mormon Prom began after LDS students complained to their parents about the dances at their high schools.
Cindy Manchester, of Pompton Plains, was an LDS youth leader in the Caldwell congregation who listened to several teens in her area, including her daughter, Danielle, raise concerns about the immodest dress, profanity, lewd behavior and excessive spending at their high school proms.
Manchester partnered with Heidi Elton, a youth leader from the Short Hills congregation, whose daughter shared the same concerns. The two mothers joined forces to create an alternative prom with a more wholesome environment. They went to their church leaders, who approved the plan, and the inaugural Mormon Prom was held in Morristown in 2006. The event is sponsored entirely by LDS churches from across the state.
"The Mormon Prom values just help keep the focus of the dance on having fun," Anna said, "and enjoying a good night out with friends."
