The winning entry in this year's Fashions in the Field competition at the Rotorua Plate Day was inspired by a piupiu, a traditional Maori skirt.
The costume called Ahu was designed by Rotorua's Adrienne Whitewood and worn by her cousin Stevie-Lee Bartle.
Ms Bartle said the pair were really nervous beforehand as it was a high fashion design but she thought they had a good chance of winning.
"I am super proud of my cousin, she is so clever at what she does. She does all the hard work and I get all the credit."
Ms Whitewood said she chose something iconic as she was looking for something representative of Rotorua.
