Fluid Bottoms

Yes. Safety is our baseline, not an afterthought.

All Petit Pli childrenswear complies with UK childrenswear regulations, including cord safety and chemical safety requirements. Our garments are tested to ensure they meet strict standards for products worn by babies and children.

Formaldehyde testing

All fabrics are tested for formaldehyde and other restricted substances in line with UK and EU regulations. Our materials are Oeko-Tex certified or tested to equivalent non-toxic standards, meaning they are verified safe for direct contact with skin.

Our softest textile

Foldwear Mini is cut from our Fluid textile, the softest and most comfortable we make, chosen for sensitive skin.

We design with aerospace precision, but always for a child's everyday life. Every stitch, fibre and finish is selected with safety, durability and responsible manufacture in mind.

If you ever have a specific question about materials or certifications, just ask.

Foldwear Mini is made from our Fluid textile, which stretches two ways and moves with dynamic, growing bodies. It is designed to adapt across occasions, from nursery to a wedding, with a comfortable fit all year round.

Three sizes cover 12 to 36 months.

Go by age: 12 to 18 months, 18 to 24 months, or 24 to 36 months. If your LittleHuman is at the top of a range, take the next one up. The size guide above has the measurements.

Yes. Two-way stretch means the fabric gives rather than strains, and it is made in London by the same team behind our adult Foldwear. If it ever rips, our Free Repair Guarantee covers it.

We're so certain your LittleHuman can't wear through Petit Pli that we offer a Free Repair Guarantee. If it ever rips or a seam gives, send it back and we fix it. Register here.

A cold, gentle machine wash takes the best care of the Fluid textile and the planet. No ironing needed. Our product care page has the full guide.
