2. Komodo

Budget: ££

Caters for UK sizes 8 – 16

Available from Immaculate Vegan

Another great choice for sustainable clothes for work is Komodo. As one of the very first ethical clothing brands – founded in 1988 – the brand has taken sustainable fashion seriously long before other retailers.

Komodo only uses premium quality organic, natural, and eco-friendly fibres. To back this up, the brand is both Global Organic Textile Standard (GOTS) certified and certified organic by the Soil Association.

Komodo manufactures its products in Kathmandu, Bali and India. It has a close working relationship with these factories – working with some of them since its inception in 1988. Komodo visits the factories regularly to ensure the people involved at every step of the process are treated with respect, receive a fair wage and are not expected to work in uncomfortable or hazardous conditions.

Komodo doesn’t stop there. Most of Komodo’s products are vegan and all are cruelty-free. It has phased out single-use plastic from its supply chain. Plus, as a member of 1% for the Planet, Komodo donates a percentage of its profits to the Sumatran Orangutan Society. This charity is restoring natural rainforests and ecosystems, through the purchase and repurposing of palm oil plantations.

3. Bibico

Budget: ££

Caters for UK sizes 8 – 16

Bibico is one of my top personal recommendations for timeless work clothes that are both sustainable and stylish. I love its consciously made dresses that make me feel amazing. I’ve been wearing this cord dress (above) for about seven years now, for both work and leisure, and it still looks great.

Bibico is rooted in slow fashion. It designs and manufactures just two collections a year. These are produced in small runs in World Fair Trade Organisation (WFTO) certified cooperatives in India and Nepal.

Every piece in the collection is crafted from the best natural and organic fabrics. These include organic cotton, linen, Tencel, and ethically sourced wool.

Bibico also gives back. It sponsors a children’s school charity in the Mumbai slums. So far it has sponsored 60 children to go to school.

For inclusively-sized sustainable work clothes with a vintage-inspired twist, then head to Joanie Clothing. This 100% vegan and size-inclusive brand takes the best bits of vintage clothing and reimagines them for the modern, everyday wardrobe.

Guided by the principle of buying less but buying better, this certified B-Corp (a brand that does right by both people and the planet) has championed slow fashion from the outset. It makes unique styles that don’t just follow the latest trends and that stand the test of time.

Joanie makes its products using environmentally friendly fabrics, such as organic cotton, sustainably produced viscose and recycled polyester. It’s currently working to ensure that all of its factories are 4-pillar SMETA audited. This is an independent audit which is designed to help protect workers from unsafe conditions, overwork, discrimination, low pay, and forced labour.

Joanie is also a SEDEX member – an ethical trade membership organisation, that works with businesses to improve working conditions in global supply chains.

To minimise waste, Joanie works with its suppliers to reduce, reuse and recycle any offcuts and deadstock fabrics. All reusable offcuts are transformed into new limited-edition garments or accessories, such as wash bags, scrunchies and more.

What we also love about Joanie is that, unlike some brands, its full collection is available in an inclusive size range.

Finally, the UK clothing brand Seasalt specialises in beautiful timeless clothing in stunning prints, many of which are perfect for work. I have a couple of Seasalt dresses that have seen me through many a meeting!

Whilst it’s not the most ethical brand out there, I commend Seasalt for offering inclusive sizing and ethical style at more affordable High Street prices.

Seasalt has been a member of the Ethical Trading Initiative (ETI) since 2018. This is a UK-based independent body that brings together companies, trade unions and non-governmental organisations to ensure compliance with international labour standards in the global supply chains of member companies. It’s also part of SEDEX.

Many of Seasalt’s clothes are made from GOTS-certified organic cotton and responsibly sourced viscose, which is made in closed-loop processes to reduce waste.

In fact, Seasalt was the very first fashion company to achieve Soil Association GOTS certification back in 2005. They’ve continued to do great things by bringing sustainability to the high street, whilst catering for a wide range of sizes.
