Having spent months in elasticated waistbands and baggy sweaters, the return to denim might feel slightly strange. But it won’t be long before you fall back in love with the versatility and ease of the fabric.

And because it transcends ages, genders, countries and styles, it’s not going anywhere. In fact, for yet another year, it dominated the spring-summer catwalks. Wales Bonner opted for button-down dresses, Balenciaga went baggy with its jeans, while Victoria Beckham added denim to her collection for the first time ever. So, while you may think it’s a fabric of the past, there are in fact a host of new pieces to invest in now.

But before you embark on your pursuit on how to reincorporate it into your wardrobe, it’s worth considering the environmental and social impact of denim. According to Greenpeace, it takes an eye-watering 7,000 litres of water to create just one pair of jeans. Much of this water waste contains harmful chemicals, pesticides and coloured dyes that cause permanent destruction to ecosystems and local communities when put back into the waterways.

While there is a long way to go to make sure denim is less harmful, the good news is, we can make more eco-conscious decisions and invest in the right brands that are doing good. With denim one of the most wanted product categories when it comes to sustainable fashion, the growing interest in more ethical consumerism provides hope. Lyst, the global fashion shopping platform, for example, noted that searches relating to sustainable denim are up 108 per cent year-on-year.

Thankfully, you don’t need to spend hours trying to find your new favourite sustainable denim brand because we’ve done the hard work for you. From the increasingly popular Nudie Jeans to affordable newcomer nu-in, there’s something for every taste.

You may notice that many of these brands aren’t at the same price point as high street alternatives, but this is because the reality is sustainable and ethical fashion does cost more. The items reflect the true cost of the materials used, as well as maintaining the high standards of the factories and caring for the people behind the clothing. While these pieces might set you back a little more than usual, they will stand the test of time and you’ll be able to enjoy them for much longer.

When selecting the labels for this round-up, we tried to choose brands that were more affordable. Beyond this, the most paramount thing was the brand’s sustainable credentials and its efforts to do better – namely opting for recycled materials and transparent supply chains.

Nudie Jeans Hanna skirt black trace denim

According to Lyst, Nudie Jeans saw a growth in demand last year and we can totally see why it’s increasing in popularity. Using a high proportion of eco-friendly materials in its products, including GOTS-certified cotton (which limits the amount of chemicals, water and wastewater from its denim products), it also reuses most offcuts to minimise waste. As a member of the Fair Wear Foundation (a non-profit that works to improve the conditions of working in garment factories), it traces its supply chain and pays living wage as standard.

IndyBest pick: Nudie Jeans Hanna skirt black trace denim: £89, Nudiejeans.com

A denim skirt is an item that transcends trends, which is why we particularly loved this one from Nudie Jeans. With a regular fit and washed black colour, it really is a wardrobe staple and it didn’t come up too short (like mini denim skirts often can). We liked that there was a full transparency report on how the skirt is produced from where the raw materials were sourced to the manufacturer and transportation. It’s a big tick from us.

While nu-in’s entire denim collection is noteworthy – and we’ve got our eye on the brand’s high rise raw hem denim skirt (£36, nu-in.com) – you simply can’t go wrong with a pair of straight-leg jeans. This particular pair are made from 100 per cent recycled cotton, and frankly, you wouldn’t know.

Lucy & Yak Easton organic denim dungarees in light wash blue

Lucy & Yak is yet another brand on a mission to prove that sustainable fashion needn’t cost a fortune, so much so it featured in our guide to the best women’s ethical fashion pieces for £50 and under. As brands go, it is doing a lot of things right. In terms of its working conditions, it ensures payment of above living wage in the final stage of production and monitors the health and safety issues by frequently visiting suppliers.

IndyBest pick: Lucy & Yak Easton organic denim dungarees in light wash blue: £65, Lucyandyak.com

These denim dungarees are made from 100 per cent certified GOTS-approved organic cotton, one of the highest standards of cotton production that makes sure strict environmental and social responsibility is adhered to in production and the entire supply chain. We were impressed with the sizing on offer, which is far better than most sustainable brands – from a size 4 regular to a size 22 regular (a leg 30), and the brand has recently introduced a longer leg 32 option for those who are a little taller. A relaxed fit, we cannot fault these retro dungas from one of our favourite brands.

IndyBest pick: Outland Denim Amy wide leg: £160, Outlanddenim.co.uk

With Gen Z declaring skinny jeans over we were excited to try out Outland Denim’s wide leg jeans. Despite being made from 100 per cent natural fibres, these had the same non-stretch properties you’d expect from your favourite pair of jeans, which worked to accentuate the bum. We can totally see why Meghan Markle is a fan of the brand (she wore the black Harriet high rise skinny (£155, Outlanddenim.co.uk) during their tour of Australia).

MUD Jeans works on a circular economy, encouraging customers to return worn jeans so they can be upcycled and sold as vintage pairs.

MUD also offers a free repairs service and a lease programme where you can rent a pair of jeans on subscription (£6.82 per month for 12 months).

IndyBest pick: MUD Jeans relax rose dip – black: £104, Mudjeans.eu

This brand knows a thing or two when it comes to denim, which became clear as soon as we put these jeans on. Made from a blend of post-consumer recycled cotton (40 per cent) and organic cotton (60 per cent), these are the same non-stretch material you’d expect from non-sustainable brands. With a straight leg cut, these accentuated the bum perfectly and didn’t fit too tightly around the thighs. A big thumbs up from us.

E.L.V. Denim mid blue match straight leg jeans

Environmental and social sustainability are at the heart of E.L.V. Denim (east London vintage). With a zero-waste ethos, it gives a second life to a fabric that would otherwise be destined for landfill. E.L.V.’s jeans are made from discarded denim that is reworked into contemporary and covetable styles, from straight leg jeans to Seventies flares. Every item in the collection is made locally in east London to keep the carbon footprint to a minimum and to support local communities. While the average new pair of jeans uses 7,000 litres of water, E.L.V. DENIM jeans use a mere seven.

IndyBest pick: E.L.V. Denim mid blue match straight leg jeans: £245, elvdenim.com

The fit of these straight legs jeans is second to none thanks to the stiff and supportive fabric. With a high waist design that offers a silhouette that accentuates the waist, while the cut hugs the bum perfectly. Each pair is slightly unique since they’re made from offcuts, but this one is made from two similar blue denim fabrics to create a vintage-look jean. We’d recommend sizing up as these tend to run small.

Tommy Hilfiger mom super high rise tapered jeans

We’re always sceptical about including high street brands in a round-up of sustainable labels often owing to greenwashing. But, Tommy Hilfiger recently joined forces with Ellen MacArthur Foundation, a non-profit that promotes a circular economy within the fashion industry, and the brand has unveiled its first circular denim collection based on traceability and recyclability. The seven-piece collection includes jeans and jackets with a focus on where the materials have come from.

There are undoubtedly some seriously notable brands in this round-up, with the likes of Lucy & Yak proving that more sustainable and eco-friendly practices needn’t cost a fortune, while Pin Denim is making waves by making vintage denim shopping that bit easier. But Nudie Jeans came up trumps not least because of its high-quality denim offering, but because of its transparency from the supplier of the raw materials to the stages of manufacturing.
