One Size Fits a Lot With New Children’s Wear Concept

Growth spurts could be a pain for parents, but one U.K. grad and James Dyson Award winner is redefining kid’s apparel with his one-size-fits-more line.

Ryan Yasin, a U.K. engineering graduate, won the U.K.’s annual James Dyson prize for his innovative prototype garments—clothes that grow with children aged between six months and three years. Considering children grow an average of seven sizes during this time, Yasin’s line, Petit Pli, could help parents save money on clothes and make more eco-conscious purchases.

“The concept of Petit Pli is built upon using materials resourcefully, because the garments grow up to seven sizes, parents are buying one, not seven different garments. This all amounts to less material waste at production, labor, transportation (CO2 emissions) and waste at end of life,” Yasin said. “Petit Pli also hopes to work on a psychological level, installing slow-fashion values in growing children and new parents.”

Petit Pli’s apparel contains waterproof shells that are pleated and can grow bi-directionally to fit a wide range of kid’s sizes. An auxetic structure enables Petit Pli apparel to stretch and accommodate children’s height and width changes. Yasin studied children’s data and designed a garment that stays the same shape throughout expansion and applied this concept to his Petit Pli line. Unlike conventional garments, Petit Pli garments are water resistant, packable, machine washable and grow with children from infant to toddler stages.

Yasin’s first Petit Pli prototype was a pair of trousers that he sewed and cooked in his oven at home. Having fit both his newborn nephew and two-year-old niece, Yasin used the prototype to better communicate the concept to parents. While interning at Ciment pleating, Yasin used videography to understand the mechanics of fabric structures. During this time, he experimented with different fabrics and eventually created the structure for the Petit Pli line.

Yasin has now tested several prototypes, and his line is still patent pending. The goal is to take Petit Pli to market and conduct more durability testing, source manufacturers with high ethical standards, collaborate with leading designers and develop a support community to further Petit Pli’s presence.
