Fit for messy adventures, our versatile, award-winning trousers are breathable, durable, lightweight and splashproof, allowing LittleHumans to summit new frontiers with ease, using the same pair from nine months to four years old.

Made from our patented ripstop fabric, they’re soft against the skin, comfortable and super durable - perfect for climbing, crawling and clambering. Each pair is created using recycled plastic bottles, so they’re lighter on the environment too.

The trousers are of course machine washable, quick drying and contract back to their smaller size. Wear them directly against the skin on warmer days, with layers underneath in colder weather, or as protection when you want to keep your LittleHuman’s outfit clean.

This charming series of vignettes follows Masumi & Towa over a year, with the changing seasons as a backdrop to Masumi’s choreography and dancing, and Towa’s transformation as he grows.

We just love it so much! <3

I bought 2 suits (in cosmic green and blue) - one for my daughter and one for my niece (almost) one year ago (and they still look the same) and we just love them so much. I keep our suit in my daughter's bag all the time, and love it because it is so versatile - I put it on the top of whatever she is wearing across seasons. In spring/summer she might just wear it on its own. She loves it and everyone notices it - when I explain that it is made of 100% ocean plastic bottles and that the suit grows across 7 sizes everyone is amazed :-) Well done Petit Pli team!

So cool! But pleat edges are a bit stiff

I bought my 2 year old a set but he complains that it feels scratchy. I felt inside and I think what he is referring to are the edges of the pleats, they are a bit stiff. I think once he grows a bit and the pleats stretch out the edges will soften. The quality is lovely, the design is super cool.. I'd LOVE a pair for myself!

Just the unpacking

Little Sara is only 3 months old by us so she still has to grow into the starting size. All i can write in my review is the unpackaging and how environment friendly it made us feel doing so. The fact that we didnt put anything into our garbage bin after a package came to us made a real impact by us. We love the whole concept sofar and we hope that Sara will love it as well.
Kepp on the good work :)

Großartig – absolut Empfehlenswert

Als Designerin und passionierte Sportlerin, habe ich meine ästhetischen und funktionellen Erwartungen an Kleidung. Als Mutter weiß ich wie schnell unser kleiner Erforscher wächst und wie wild es bei all den aufregenden Abendteuern zugehen kann. Mit seinem Petit Pli Set hat unser Kleiner endlich ein Outfit dass nicht nur bis ins letzte Detail mit viel Aufmerksamkeit und Verständnis designed wurde sondern auch eines dass viele Jahre passen wird und die Idee von Nachhaltigkeit dadurch von einem ganz neuen Winkel aus beleuchtet.

Gala’s Suit

We really love P P’s clothes: they are light, versatile and look great! The only thing to point out is that sometimes, when worn, it takes time for the fabric to get back in shape and looks a bit amorphous. But otherwise, it is all fantastic
