7 UK Organic Clothing Brands To Cotton On To In 2024

Looking to make your wardrobe more eco-friendly? Then here are the best organic clothing brands to cotton on to in 2023, for both men and women.

Some brands have paid to be featured here – identifiable by the AD tag after the brand name. We only select brands that we genuinely believe are doing good things for people and the planet.

While you may have been popping organic food into your shopping basket for years, have you ever thought about making your wardrobe more organic?

If so, then cotton is a great place to start. This natural fibre is both plastic-free and vegan-friendly, meaning that it doesn’t contribute to the microplastic problem or animal cruelty.

However, one big problem is that conventional cotton is grown with pesticides and fertilisers – some of which can be highly toxic. And data about pesticide usage in the cotton industry is silenced. This means we don’t know for certain the impact that the cotton industry has on the environment.

What we do know is that some chemicals used in conventional cotton production have been linked to health problems in those involved in its production – including farmers and pickers. We also know that pesticide use can result in the loss of biodiversity and can contaminate water supplies.

Whilst there are a few options when it comes to purchasing cotton – such as BCI Cotton – certified organic cotton is the only cotton that is guaranteed to be grown without pesticides and fertilisers. This makes organic cotton an altogether better choice that’s healthier for all.

Quick Links To Organic Cotton Clothing Brands

If you are looking to make your wardrobe more organic, here are the best ethical and sustainable clothing brands using organic cotton in their collections.

Use these quick links to jump to information about each brand, or keep scrolling for the full details.

Who Accredits Organic Clothing Brands?

There are currently only two ways to be sure that your clothing has been produced organically and made in factories adhering to strict environmental and social standards.

The piece of clothing, or the brand’s website will have either a Global Organic Textile Standard (GOTS) logo or a Soil Association Organic logo. In some cases, both logos will be displayed.

GOTS

GOTS is the leading textile processing standard for organic fibres.

As a voluntary standard, GOTS-approved clothing must be made from at least 70% organic fibres. Products must also never contain potentially harmful chemicals which can be found in clothing made from non-organic fabrics.

This certification additionally includes social criteria. So when you see the logo this means that the brand has safe working conditions, no child labour, and allows no discrimination.

GOTS Certification is carried out by independent experts who physically inspect companies and facilities to verify standards are met.

The Soil Association

In the UK, the Soil Association is the largest UK certification body for GOTS, so it has the same criteria as GOTS.

This accreditation demonstrates that the cotton fibre was produced organically and processed to strict environmental standards under good working conditions in the factories.

This logo also ensures that the organic cotton has been certified by an independent, third party along the whole supply chain.

The Organic Clothing Brands To Know For Men & Women

AYA Organic Clothing | AD

Organic cotton clothing brand AYA was launched at the beginning of 2022 with the goal of making luxurious cotton clothing without the use of any plastics or harmful chemicals.

Seeking to revolutionise how fashion is made, by embracing what is best for people and the planet, the brand seeks to bring about positive change in the fashion industry.

Whilst it is early days for AYA, impressively the brand is making huge strides.

For a start, every item of clothing is made from organic Pima cotton – a super soft, breathable and durable cotton. This type of cotton is more resistant to bobbling as its fibres are longer. This means your clothes stay looking better for longer.

What’s more, all of AYA’s clothing is completely free from plastic – even hidden types of plastic.

All the threads AYA uses are made from cotton, rather than traditional synthetic materials, such as nylon. Its elastic bands are also free from plastics – instead made from natural rubber and cotton. Even the labels are made from 100% organic cotton fabric which is printed with GOTS-certified ink. This means its clothing doesn’t contribute to microplastic.

And there’s more to love. Each item in AYA’s collection comes with unique colour options I haven’t seen anywhere else. Here you can choose between undyed cotton, low-impact synthetic dyes or plant dyes, depending on your preferences.

TenTree

TenTree is a Canadian ethical clothing company, now available in the UK via Wildbounds, that makes stylish ethically and sustainably produced outdoor and casual wear from eco-friendly fabrics.

TenTree also plants 10 trees for every item you purchase – hence the name! This is carried out in partnership with various tree-planting charities, such as Trees for the Future, to ensure meaningful and sustainable replanting. 

Of course, it’s not just about the trees. As a certified B-Corp, every TenTree item is ethically made using sustainable fabrics. 

Organic cotton is a key element of TenTree’s range of clothing. Find organic hoodies, jogging bottoms and t-shirts in stylish designs that you’ll want to wear time and time again.

My only criticism is that I couldn’t find any information on if TenTree’s organic cotton is certified organic or not. The only thing I have found is that its cotton is Fairtrade certified. I have asked TenTree for more information, and I’ll update this post when I hear back.

Thought Clothing – available at John Lewis – makes easy-to-wear ethical clothes for men and women that are both sustainable and contemporary.

Thought’s approach to ethical fashion is one to be commended. The brand uses only certified natural and recycled fibres and fabrics and makes its clothes ethically.

Thought also makes its clothes from start to finish in the same country. This prevents them from being shipped from country to country, for example, to add buttons or zips, which is a common practice within the fashion industry.

GOTS-certified organic cotton is a key fabric in the brand’s wide range of men’s and women’s clothing. Here you’ll find a whole range of wardrobe staples, from ethical jeans to cosy sustainable socks, all made from organic cotton.

What’s more, most of Komodo’s products are vegan and all are cruelty-free. Komodo also no longer have single-use plastic in its supply chain.
