This year's competition has some innovative ideas depicting the theme Bras for a Cause Goes to the Movies, she said.
First-time competitors Karen Volpei and Robin McCary, both of Burbank, submitted two entries: Popcorn and Pearls and A Night at the Oscars.
Their Popcorn and Pearls entry was very impressive, Lefkovits said.
"It's a pretty bra," she said. "There are pearls that go up the straps and pearls along the edge and they put movie tickets with it."
While it's one of three bras using popcorn in the design, each is different, Lefkovits said.
"It's amazing what people come up with every year," she said. "No two have been alike yet."
Participating in the event is a personal thing for Volpei and McCary.
Volpei had a breast cancer scare three years ago and both her parents died from lung cancer, she said.
"I've participated for many cancer events," she said. "Once you have walked that path, you understand how important it is to help fight for the cause."
McCary's sister-in-law is a two-time survivor of breast cancer, she said, and her husband's mother died from it.
"We're all touched by it somehow, a friend of a friend, co-worker or family member," she said.
"I feel honored I get to be a part of Bras for a Cause."
Not only is the cause a great one, but also people really have fun decorating the bras, Lefkovits said.
"They are laughing while they are decorating them and scurrying around town looking for decorations," she said. "My phone just keeps ringing and people are laughing on the other end."
This year, a bra has even come from overseas, from a Soroptimist club in Burnley, England, Lefkovits said.
Along with the bra, which is decorated with the British flag, the group sent several tabloids, a signed photo of the Prime Minister and film clips from the film, "The Queen."
