The fundraiser raised money to pay for 40 New Zealand children with HIV to attend Camp Good Time in Australia.
The fundraiser, known as Positively Glamorous, came about after the organisers were unable to get New Zealand Fashion Week to pay attention to the AIDS epidemic.
"[I was] talking to Chris from Mint Condition, he said ‘don’t worry about Fashion Week, lets do it outside of Fashion Week, it will be great’, and he was right," said organiser Jane Bruning.
The event was set up in just two weeks with the help of 20 designers who signed up to create an outfit each.
All the designers worked well together and were keen to play down any suggestions of backstage backstabbing.
"No, no, no, it never happens," said designer Alex Jaeha. "We are just tweaking little things and helping out."
The only limit placed on the designers was to incorporate a red ribbon into their theme. A red ribbon is a symbol of solidarity for people living with HIV/AIDS.
Radio personality Noelle McCarthy, who has recently been accused of plagiarism, hosted the event.
"New Zealand, because of our location, is one of the first places in the world to celebrate and support people in the world who are living with HIV," she said.
Nearly 3000 New Zealanders have been diagnosed with HIV since the epidemic began.
