It's a good thing Imogen Smee enjoys dressing up.
The 15-year-old Wollongong High School of the Performing Arts student has five costume changes for her roles in this year's Southern Stars production - a princess, a superhero, a 1920s office outfit, a contemporary pop costume and a Spice Girl.
But the quick wardrobe switches don't faze her.
"I've been dressing up since I was out of the womb," she joked.
As well as taking part in group performances, she has a solo singing Today was a Fairytale by Taylor Swift.
"[The audition] was so scary because lots of the people in the auditions were from my school and I had heard a lot of them sing before and knew they were talented singers," she said.
Nearly 3000 students from almost 90 public schools across the region will take part in this year's show, which is called #webelieve 2014, an exploration of how beliefs change throughout our lives.
Southern Stars is on at the WIN Entertainment Centre on August 29 and 30. Tickets are available through www.ticketmaster.com
