That's because the ball is a fundraiser for the Park City Institute's student outreach programs.
Programs include the tutoring center known as the Mega Genius and I.Q. Supply Store, which opened in 2010.
"This year, our numbers have reached capacity more days than not," Orr told The Park Record. "We provide free tutoring after school and the focus is on literacy, but we do help with other homework as well."
The money raised will also help provide more artist workshops from dancers, actors and singers who perform during the Park City Institute's winter and summer seasons.
"What people may not know is that having these artists costs an extra fee on top of the performance fee," Orr said. "When they do workshops, we are literally asking them to do another performance. Plus, we have to play for additional lodging."
These workshops introduce Summit County students to various art forms that they may not otherwise have the chance to experience.
"Just last week we had an extraordinary outreach session with Cedar Lake Contemporary Ballet," said Orr. "One of the students said, 'That wasn't ballet. That was fabulous.'"
Last year, the Saints & Sinners Ball provided $75,000 towards the outreach programs, and the bulk of the money raised through the Saints & Sinners Ball come from an auction that is held following dinner and some of the items are unique to visual and performance art.
"Boz Scaggs was here a few weeks ago and it was a fabulous, sold-out show," Orr said. "We got him to sign a guitar."
Other past performers who have signed guitars for the auction include Natalie Maines from the Dixie Chicks, Jewel and members of the bands Los Lobos and Delta Rae.
"We also are auctioning off a small, Linus-sized piano signed by Bruce Hornsby and a violin signed by the cast of Celtic Night," Orr said. "We also are including artwork and a portrait session from one of the artists represented by Terzian Gallery."
Sports and leisure are represented in the auction as well.
"We also have a New York Giants helmet signed by the team after the 2007 Super Bowl win," Orr said. "We are also offering a stay at a private home in the Bahamas and a great beach cabin in La Joya."
Other auction items include dinners and spa packages. However, the ultimate auction item is a Sundance Film Festival package for two that includes two reserved seats at the Eccles Center.
"Other than Mr. [Robert] Redford there is no one else who has that privilege," Orr said with a laugh. "But as good as all that is, the real magic of the item is the free parking that's included."
Over the past three years, the Saints & Sinners Ball has become more than a fundraiser, but a fun costume party.
"Park City people love to dress up," Orr said. "Some people have attended regularly and become seasoned in how they like to attend and dress up.
"We've had every variation of saint and sinner but there is always something new," she said. "There is always a surprise."
Past costumes include polygamous leader Warren Jeffs and one of his brides, cross-dressers, police officers and the expected number of angels, devils, pregnant nuns, school girls and bad boys, Orr said.
"Some folks come in ball gowns, because it is a ball," she said. "And others come in street clothes and that's fine, too."
Music will be provided by the Joe Muscolino Band.
"He played for us on New Year's Eve after Bernadette Peters and he was so fun that people wanted to dance all night long," Orr said.
Another thing that makes the Saints & Sinners Ball different than other fundraisers are the shenanigans.
"These are playful, unexpected things that will go on all evening," Orr said. "We do these things because the event is close to St. Patrick's Day and it's fun to cause a little mischief. We're not there to embarrass anyone, so these are just fun little things."
Park City Institute will host its third annual Saints & Sinner Ball at St. Regis Deer Valley on Saturday, March 15, beginning at 6 p.m. Tickets to the Saints & Sinners Ball are $175 per person or $1,600 for a table of 10.
