Horsham pin-up model Laine Munn heads for Las Vegas

Mrs Munn, also known as Miss Ruby Rabbit, was chosen as a

contestant for the Miss Viva Las Vegas Pin-up Competition in April.

"Initially, I was told the contestants had to be voted for, but the judges would also pick four girls to skip the voting and compete at the competition," she said.

"When voting opened I was trying hard to get votes, but then found out I was chosen by the judges.

"It was incredible and I was so surprised. Out of almost 200 entrants, I was one of four chosen."

Mrs Munn said the competition would involve answering questions on stage.

"Unlike other competitions, I need to win over the audience at this competition instead of the judges, so I will try to think of a quirky way to present myself so the audience doesn't forget me," she said.

"Hopefully it will bring across my personality as well."

Mrs Munn started doing pin-up modelling in 2012.

"I found that I was putting on weight and I was unhappy with how I was feeling in modern fashions," she said.

"I had a friend who dressed in rockabilly style clothing, so I researched it and found a pin-up competition I could enter.

"I found it was a good way to build my self-confidence."

Mrs Munn was runner-up in the Miss Pin-up Australia competition, which was the first competition she entered.

"I then entered a few more competitions and had similar success, which sparked me to enter the Las Vegas competition," she said.

Mrs Munn said the reason she started pin-up was to improve her body confidence.

"I found that since I have been winning competitions, a lot of girls have approached me saying they felt better about themselves because of what I was accomplishing," she said.

"It promotes a better body image than what the magazines are portraying."

Mrs Munn said she could not wait to go to Las Vegas.

"It will be an experience of a lifetime and I am happy just to be competing," she said.

Mrs Munn said she would

encourage more women to become involved in pin-up.

"The style and the culture of pin-up is very supportive of women who are lacking in self-confidence," she said.

Mrs Munn is now raising money for her trip to Las Vegas. She has had support from the Little Desert Rockers, which pledged $500.

"I just want to thank them for supporting me and getting behind me," she said.
