Founded by Ryan Mario Yasin in London in 2017, Petit Pli was launched to address the dull & ill fitting children's clothes on the market; particularly for Ronja & Viggo, his niece and nephew.

The turning point came when Ryan had finally found a garment he liked for Viggo, but by the time he travelled to Denmark to gift it, it had already been outgrown. Trained as an aeronautical engineer, and specialising in deployable structures, Ryan decided that he would find the solution to ill-fitting childrens clothes. Petit Pli strives to create the most advanced technical children's clothing in the world.
