Petit Pli creates clothes that grow.

Petit Pli constructs the most advanced technical children’s clothing in the world. Petit Pli’s recycled, versatile & rainproof garments are embedded with a patent pending structure that allows them to grow bi-directionally to custom fit children from 9 months to 4 years of age. Petit Pli's designs are a desirable way to be sustainable & encourage sustainable values in the next generation.


Petit Pli is a wearable technology company. Petit Pli aims to clothe the future of humanity, starting with the next generation. London-based Petit Pli was founded in 2017, by trained aeronautical engineer Ryan Mario Yasin. Shortly after Ryan gifted clothes to his newborn nephew, they were already too small! This experience served as a signal: childrenswear today fails to recognise the dynamic & rapidly changing bodies of Earth’s LittleHumans. 

Inspired by aerospace engineering, Petit Pli’s continuous size adjustment is a new way of approaching garment design - one suitable to high growth rates in children. Petit Pli uses technical materials that are ultra-lightweight, reinforced, rainproof and breathable because children are extreme athletes.

Childrenswear - version 2.0

Exploration and materiality are key to Petit Pli. Were it not for Petit Pli’s love & understanding of materials, we would never have been able to answer the needs of parents & children around the world. We seek to encourage children to explore the world around them and to push humanity through its second skin.

The colours of the second Petit Pli series, C-2.0, explore the culmination of humankind’s technological advancements, from electricity to manufacturing and aerodynamics. The Petit Pli design team paid close attention to the various tones that would be present in such a characteristic form, with each garment containing hundreds of colour gradients that are a result of their unique three-dimensional form interacting with surrounding light. The almost pixelated microgrid structure within the fabric is highlighted with a sheen that reflects the dynamism of an electric current.


The concept of Petit Pli is built upon using materials sustainably. Petit Pli's designs significantly reduce waste and CO2 emissions at the point of production, distribution and after purchase. Our garments grow up to 7 sizes – that’s 1 Petit Pli garment purchased in place of 7 traditional ones.

Petit Pli suits are made from recycled fabrics & have a monofibre construction. Along with this, we’ve partnered with a manufacturer in Portugal that derives 30% of their energy from solar panels.

Through its approach towards sustainability, Petit Pli hopes to instil slow-fashion values in growing children by inspiring them to value longevity and innovation in some of the most intimate products our lives - clothes!
