The clothing that grows with your child

Any parent will know the frustration of buying clothes for young children – they fit for about 3 weeks and then your child has grown again and you’re back down the shops.  On average a child will grow through seven different sizes in their first two years, costing an eye-watering £2,000 before they even reach the age of three.

This year’s James Dyson Award winner has provided a solution to your wallet woes, in the form of an incredible garment that can actually grow along with a small child. 24-year-old Ryan Yasin, a recent graduate from the Royal College of Art and Imperial College London, has developed a set of clothing called Petit Pli, that are not only waterproof but also compact enough to fit in your pocket.

To pull off this trickery, inventor Ryan adopted Negative Poisson’s ratio. The ratio describes the state of a material when it is stretched, called auxetics. By using heat treatments, Ryan was able to give the fabric auxetic properties, meaning it can stretch to many times its original size.

Ryan has won £2,000 and moves into the International part of the competition, with the chance of winning £30,000.
