Buying baby clothes starts to add up, particularly if you’ve also got toddlers and young children too. It can be tough finding clothing that is good quality and sustainable without the high cost.

And while you might be lucky to have access to hand-me-downs from friends and family, or find some bargains at your local charity shop, there’s no guarantee that the clothes you get will fit. On top of this, children’s clothing is one of the largest contributors to the 350,000 tonnes of clothing that clogs up UK landfills each year. So here’s a good place to start if you’re interested in some more sustainable children’s clothes.

At Y’earn, we’re always looking for ways to help parents find the latest eco-friendly options. We provide sustainable choices where possible. We pay attention to clothing brands that are focused on decreasing their carbon footprint so you don’t have to try and figure this out too. Shopping for children’s clothes is important. Whether that be sustainable children’s clothing for wet and cold weather, or sustainable school uniform. No matter what you’re looking for, here are our favourite brands that provide sustainable children’s clothing that is built to last, while also taking care of the planet.

Brands that use organic cotton and wool

Babygrows, t-shirts, trousers, and dresses are foundational parts of many children’s wardrobes. And while you can certainly find cheaper options in discount department stores, a more sustainable and eco-friendly choice is to find clothing that is made using organic materials, such as cotton and wool.


This Swedish children’s fashion brand offers a range of clothing made from 100% organic cotton and recycled materials wherever possible. They have cute dresses for special occasions and offer matching items throughout their ranges.

Kit & Kin

This sustainable brand started out as a skincare products company and when they launched their babywear line, the ethos of the company flowed through too. They offer 100% organic cotton for their entire sustainable baby clothing range, which goes up to 24-months. They have adorable cardigans, perfect for the cooler months. A lot of the babywear items are unisex, allowing them to be passed on to younger generations too.


Mori offers a children’s wear line that ranges from baby up to six years. They use 100% organic cotton and bamboo blends in their clothing. Their clothing is moisture-wicking and breathable, perfect for active kids.

Brands that reuse plastics

Wellington boots, raincoats, parkas, and puffas are common options for older children who love to play outside, rain, sun, or snow. Typically, these types of clothing items are made with synthetic low-quality materials that are easily damaged and have a large carbon footprint. You’ll want to opt for products that are more eco-friendly and PVC-free.

Muddy Puddles

In 2020 Muddy Puddles launched their UV protective swimwear line. The entire line is made from recycled plastic bottles. The swimwear line is called “Save Our Oceans Collection”. It has UPF 50+ built-in, making this line not only sustainable but also ensures that your kids are safe when out in the sun.

Polarn O.Pyret

With the goal of making each product last at least three generations, you’ll find their clothing made from recycled polyamide (from old fishing nets) and recycled plastic in its polyester blended material. They also offer a free repair service! If you’ve got a broken zip or lose a popper, no matter when you purchased, simply pop into your local store and they will fix it.


This outerwear brand offers kids clothing that is made from 100% recycled PET plastic bottles. Their most popular reversible puffa is an investment, but if you purchase a size larger, you’ll get more wear. They out fit kids up to the age of 14.

Brands that donate funds to good causes 

As your baby gets older, not only will they grow, but the need for more durable clothing will grow too. Along with adding durable and sustainable clothing items to your child’s wardrobe, you also have the ability to buy from baby clothes brands that donate to good causes too. 


This children’s label offers bright rainwear in PVC-free materials and uses 100% organic cotton for their other clothing items. You’ll find clothing options for up to the ages of 10-12 years. They also support several charities too. They sponsor an orphanage in India and give a percentage of their profits to help environmental organisations

Kit & Kin

This company gets a special mention again because not only do they provide a babywear line that is 100% made from organic cotton, they also help conserve rainforests and provide ongoing funds to healthcare clinics for women in Sierra Santa Cruz. This is in partnership with the World Land Trust. This is a well-known British charity that’s dedicated to the sustainability of conservation.

From Babies with Love

This baby clothing brand is unique among clothing brands. Not only do they offer clothing that is made from certified organic cotton they also donate all their profits to charities that help disadvantaged children around the world. With the focus on helping support orphaned and abandoned children globally. If you’re looking for a gift, their baby sets are adorable.

Brands that offer subscriptions

If you have a baby and a toddler, it’s likely that you’re going to need new clothing at a fairly constant pace. Especially if your children are active and love to play outside. They’ll need trousers and long-sleeve tops for winter and shorts and tees for summer.

The Little Loop

Little loop is a clothing rental service for kids that we love here at Y’earn! Little Loop offers the perfect no-compromise, truly sustainable solution to clothing your little people as you can opt for items that are brand new or rented a couple of times. Renting a super stylish wardrobe, direct from your favourite brands, with swaps as often as you like as they grow. You’ll be helping to save the planet, time, space & money too! We think it’s a no brainer!

The Little Rental Co

This babywear clothing company offers organic cotton clothing at an affordable price. You simply rent what you need and return it when you no longer need it. You’re likely to save on average £1331.84 over a two-year period! You can rent clothing for children up to 24 months old.

Graceful Changes

Graceful Changes offer a subscription service for kids’ clothing that ranges from babies right through to toddlers (newborn to age four). They create high-quality and ethical clothing parcels that are shipped out as needed. You can choose the items you need for each parcel you need and there is a simple return option when you need to move to the next size up.

Sustainable clothing for all

We know that these brands are more expensive than getting a coat from Primark but they’re built to last so you can pass them down to younger siblings or friends kids (and let’s face it, Primark is contributing to the fast fashion mindset which is expensive to the planet!). Renting is a cheap option if you’re not planning to put your child in a new outfit every week, but if price is an issue then why not pop to your local charity shop and opt for some pre-loved clothing for your little one?

Second-hand apps are also a great option and let you find great brands from the comfort of your sofa! There are so many out there, we suggest you take a look at Vinted, Depop or even eBay! That’s why we love seeing initiatives from brands like Marks & Spencer which encourage people to pass on items their children have outgrown, so don’t forget to pass your coats on!

Once your child has outgrown their clothes, why not consider donating them? Take a look at our blog focusing on clothing poverty and how you can help for some suggestions on where and how you can donate.

Don’t forget that once you get clothes you can extend their life… According to the British charity WRAP, extending the active life of all clothing by nine months would reduce the annual carbon, water and waste footprints of UK clothing by 20-30 per cent. You can also preempt damage by examining clothing and spotting any weak points.
