Winner: Wearable design of the year 2018. Petit Pli kids clothes were designed by Ryan Mario Yasin to stretch as children grow using a pleating system.

Yasin, who is a graduate of the Royal College of Art masters programme in Innovation Design Engineering, created Petit Pli after buying clothes for his nephew that no longer fit by the time they arrived.

"Children outgrow their clothes in a matter of a few months, yet we clothe them in miniaturised adult clothing, as opposed to designing them from the ground up. With 11 million children in the UK, I thought it was time we redesigned children's garments," Yasin told Dezeen.

Yasin used his background as an aeronautical engineer to devise the pleating system that allows the rainproof garments to "unpack" when pulled, so they stretch bi-directionally to custom fit a range of 7 sizes.

The designer hopes that by creating children's clothes that last longer, it will help reduce the huge amount of waste generated by the fashion industry. Petit Pli aims to help create future generations that value longevity and innovation in production.

Judges comments: "A sustainable yet elegant design for the most important people in the world."
