Petit Pli Versatile Bottoms for Babies
Last updated: 24 October 2026
Petit Pli Versatile Bottoms are pleated trousers that grow with your child, made from patented ripstop spun from recycled bottles. The TinyHuman size for babies from 0 to 12 months costs £60 and grows through four sizes, which Petit Pli prices at £15 per size. New customers get £20 off a first order of £60 or more through our link, so one pair comes to £40.

What Petit Pli Versatile Bottoms are
Petit Pli is a London material technology company, led by engineers and designers. Its trousers use a pleated fabric that opens out as a child grows, so the same pair keeps fitting as the waist and legs lengthen. Petit Pli calls them award-winning and says they grow through seven sizes across the full range.
For babies, the TinyHuman version covers 0 to 12 months. On a size chart that means a waist from 46 to 52cm and an outside leg from 23 to 47cm, from the smallest setting to fully grown.
What they do
- Grow with your child: the pleats open out, so one pair covers four baby sizes in TinyHuman.
- Shrug off weather: the recycled ripstop has a water-repellent finish that is free of fluorocarbons.
- Move with them: Petit Pli designs them for crawling, climbing and clambering.
- Wash easily: a gentle 30°C wash, laid flat to dry.

Who Petit Pli Versatile Bottoms suit
- New parents: one pair covers 0 to 12 months, where ordinary trousers come in four separate sizes.
- Gift buyers: sizing a present for a newborn is guesswork, and clothes that grow take some of the risk out of it.
- Outdoor families: the ripstop is splashproof for buggy walks and muddy parks.
Our Petit Pli discount code page explains how the £20 offer works step by step.
The limits
£60 is a lot for baby trousers. The case for them is that one pair replaces up to four sizes in the TinyHuman range, and the code takes £20 off a first order.
The care is fussier than cotton. Fabric softener stops the water-repellent finish working, and they cannot go in the tumble dryer.
Colours sell out. Seven of the twelve TinyHuman colours were unavailable on Petit Pli's shop, so pick a size first and then see what is left.
The water-repellent finish fades with wear and washing. Petit Pli suggests a reproofing spray once rain stops beading on the fabric.
