The show has a range of sections, including Dressed to Kilt - an open section where designers choose their own theme or concept; Re-invent, Recycle and Re-Use - where designers are tasked with constructing a piece of wearable art; and The Engine Room - for those keen on testing their engineering skills.
"I looked at some [designs] and I was totally gobsmacked. I'm not an arty person so I don't even know how they can see that idea in their head and then make it come to fruition."
Ms Pettit said it was not uncommon for entrants to begin work on their designs a year in advance.
She said that after the show some designers would already be thinking about next year's entry.
There was space for about 500 people per show and the award night and the matinee show were already sold out.
People would need to get in quick because there were fewer than 100 tickets left for the Friday show, Ms Pettit said.
"It's a huge community thing and they get right behind it. We have a huge team of volunteers in the background."
