Petit Pli clothing features permanent pleats that allow it to expand in all directions, growing up to six sizes. The idea came to Yasin when he was buying clothes for his nephew, only to find that by the time they were ready to be worn, the child had already outgrown them.

Petit Pli clothing is a unique garment that can grow with you. It has permanent pleats, enabling it to stretch in all directions and expand up to six sizes. Yasin applied his background in aerospace engineering from Imperial College London to develop an auxetic material that widens when stretched and contracts when compressed. This means the clothing expands when unpacked.

It can be waterproof and windproof, making it ideal for children aged six months to 36 months, and now also available for adults. The clothing is made from a patented synthetic material with a hydrophobic coating, making it water-resistant.
