Trust Me, I’m a Sustainability Editor – 18 Stylish and Sustainable Launches That I Can’t Stop Thinking About

Secondhand September may be over for another year, but one thing it proved? Sustainable fashion isn’t going anywhere for 2025.

Trust me, I should know - I’m the Senior Sustainability Editor here at MC UK who’s a firm believer in the power of slow fashion and a buy less mentality. I’ve had the pleasure of judging both the Marie Claire UK Sustainability Awards and the Positive Luxury awards in recent years, both respected institutions that reward innovation, real change and higher standards across the industry.

I’m also incredibly privileged to know world-renowned industry experts, scientists, game-changers and professors day in, day out, who are right at the forefront of the climate crisis and dedicating their lives to building a better tomorrow.

All of that to say - I’ve always got my eye out for the latest eco-friendly, innovative and genuinely interesting launches that I’d want to shop, use, or visit. And the below tick all of the right boxes - they’re seriously stylish, great quality, and also put people and planet first.

While it can feel totally overwhelming and a little stick-your-head-in-the-sand at times, let this be a guide to the new launches to have on your radar for 2025. Because doing your bit needn’t be overwhelming.

The high street has had a makeover - and it's starting to pair sustainability with style

There have been some seriously impressive launches from certified B Corp fashion brands in the past few years. And while I know what you’re thinking - buying new isn’t sustainable, right? - I’d counter you on that one.

You see, we’re all human. We all need new clothes at some point, regardless of how well we look after our wardrobe items or invest in their repair. Which is where genuinely innovative brands come in, making it that bit easier to shop with a conscience.

This year, brands seem to be balancing sustainability with style, elevating what it means to be a brand with a conscience. Because often, it really is as simple as swerving greenwashing fast fashion brands and buying your clothes from certified brands, like B Corp brands, instead.

On that note, sustainable athleisurewear brand Tala opens its second store in Westfield tomorrow, and I was lucky enough to head down to check it out ahead of opening. (Spoiler alert: it's great).

Not only does Tala design seriously elevated and cool girl-coded active and athleisurewear, as well as coats, made-to-support-your-every-move essentials and sleepwear, but they're also a pioneer in the sustainable activewear sphere. Lots of their designs are made from lower-impact, recycled and natural fibres, and their packaging is 100% plastic-free and includes plantable swing tags.

Another fun fact? Tala's London HQ runs on 100% renewable energy. Their second store opening in under six months, head down this weekend for free gifts, snacks, and drinks, a live DJ, and in-store only exclusives.

Stripe + Stare is another example. The female-founded, British and B Corp-certified brand produces confidence–boosting, stylish and deliciously comfortable underwear made from TENCEL’s Micro x Modal, a fabric sourced from Austria and made from Beechwood Trees.

This month, they've launched their second collaboration with renowned fashion brand Rixo. Their second collection includes sustainably made underwear, pyjamas and bodysuits in bold, eye-catching animal and floral prints, designed to celebrate the pleasure in everyday and the contentment of being in your own space. My personal favourites are the leopard print pyjamas - I haven't taken them off since they arrived.

Another fun fact about the brand? Their knickers are 95% biodegradable—simply cut off the lace, bury them in your garden, and, in time, they will disappear.

And that's not the only exciting collab they've been cooking up. Just last month, they launched a gorgeous pyjama and underwear collaboration with nutritionist and best-selling author Emily English - and having tested the collection before it launched, I can confirm it's deliciously soft and wearable for both day and night.

Think matcha green and blueberry shades, fun, food-inspired prints and soft-as-anything, sustainable fabrics. Sizes range from XS to 4X (UK 6-22).

Also relatively new in at S&S - can you tell I'm a fan of the brand?, they recently launched their first ever lace collection of underwear. Aptly called "Eco Lace," the designs took years to perfect and are crafted from buttery-soft TENCEL™ fibres and 85% recycled lace. Having tested it, it's gorgeously delicate and flatters and fits like a dream.

Sustainable clothing brand and B Corp-certified Omnes has also been hard at work this month, launching a limited-edition detergent and fabric spray that aims to elevate the art and ritual of clothing care.

Collaborating with B-Corp certified zero-waste refill company Fill Refill, the Neroli-scented laundry solutions are seriously luxurious and aim to extend the lifespan of your clothing, as well as promote re-wear culture.

“No one sets out to treat their wardrobe as disposable, and yet, every year we send thousands of tonnes of textile waste to landfill. Preserving the lifespan of the clothing we already own is a preventative action we can all take to reduce the impact our wardrobes have on the planet," shares OMNES founder Jordan Razavi.

“Over-washing is often an overlooked topic in the fashion industry, one that has long-term effects, which is why we collaborated with FILL REFILL. We wanted to provide customers with the tools and know-how to look after their garments so that they can continue to wear them year after year.”

With industry reports revealing that British consumers are re-wearing their outfits 35% less than they did 15 years ago, there's no time like the present to invest in genuinely impactful laundry solutions that prolong the lifespan of your clothes.

I've also been loving Chelsea Peers recently. It’s one of my current favourite brands for a number of reasons, but largely because it’s a certified B Corp that stocks gorgeous organic loungewear, pyjamas and activewear. The items really are next level, and their new lounge collection, in particular, is butter soft, easy to wear, and elevated, making chic dressing eco-friendly, too.

I’ve also been loving the designs from UK-based fashion label Saint + Sofia, whose latest collection epitomises festival boho chic with timeless design. While the brand isn’t a certified B Corp, they do score an “It’s a start” on rating site Good On You, who acknowledge that the brand is doing a good job of using lower-impact materials, including organic cotton, recycled packaging, and limited production runs. The brand has slow fashion as its core, and uses natural or recycled materials in all of their clothes, delivering items in biodegradable packaging, to boot.

Other sustainable brands that are definitely worth having on your radar include By Glaze - ethereal, nature-inspired jewellery pieces that’ll last a lifetime, and Piglet In Bed - a brand born in West Sussex that produces pastel and neutral hued linens that promise to boost any interior.

Even the likes of fashion brands Ferragamo and Ryoko Rain are launching sustainable collections this year, and I for one can’t wait to see them.

Bottom line? Buying less but investing well really does have the power to change the world.

Bicester Village is making it easier than ever to invest in forever items

I recently had the pleasure of heading to Oxfordshire’s luxury designer shopping outlet, Bicester Village, and was pleasantly surprised.

Now, I know what you’re thinking, but hear me out on this one, as I was quite impressed by the variety of vintage and pre-loved items on offer throughout the stores. One in particular that caught my eye was the Mulberry Exchange, an entire pre-loved bag collection. Each item has been lovingly refurbished by the restoration artisans in their Somerset workshops, with the aim to craft and refurbish bags that’ll then last you a lifetime and be passed down from generation to generation.

Bicester also host pop-up events over the course of the year where you can get your hands on unique vintage and pre-loved clothes, handbags, shoes, sunglasses and more, so it’s worth keeping your eyes peeled if you’re in the market for some forever items.

The wide range of luxury items on sale also gives you the opportunity to buy investment pieces that’ll stand the test of time at more affordable prices. There are also plenty of B Corp brands to shop at the outlet, including Neom, Elemis, Bamford, The White Company, L’Occitane, and Ganni.

Fancy heading yourself? Bicester Village is located just 46 minutes by direct train from London Marylebone and has over 150 boutiques, not to mention restaurants, cafes and shopping services.

Repairing, upcycling, or breathing new life into your clothes has never been easier

New on the upcycling, redesign and repair scene comes the app Loom. I’ve been quite amazed at how easy it is to navigate, meaning that the pile of clothes you’ve had sitting in your study for alterations or repairs can finally have their day.

It’s really as simple as uploading an image of your item and detailing what exactly it is that you’d like repaired or redesigned. Then, you’re paired with a designer, who’ll get to work with bringing your creation to life.

The possibilities really are endless - whether it’s a simple leg shortening, a tear repair, or you’d like to breathe some totally new life into an old item you don’t wear, apps like Loom are proving that breathing new life into your old clothes really needn’t be complicated.

And neither has renting amazing clothes for a fraction of their retail price

Rental fashion has soared in popularity over the past few years, with sites like By Rotation and Hurr becoming firm favourites for renting occasion wear.

But my current go-to is Rites - and I can say first-hand that the site offers the most seamless and stress-free delivery and pickup service of all of the rental options out there. With designer items from Ganni, Rotate, Self Portrait, SIR and more, their collection is carefully curated to ensure there's something to suit everyone.

You're really spoilt for choice - plus, if you're unsure about how an item may look on you and would like to try it on IRL, you can head to their Broadway Market store.

Plus, sustainable marketplaces are putting independent, innovative brands on the map

Last but by no means least, Wolf & Badger has long been one of my go-to sustainable brand marketplaces, but some of the brands currently listed on the site are really gorgeous.

If you haven't heard of the B-Corp certified brand before, it's an ethical fashion destination stocking an extensive range of independent, eco-friendly brands. Think Selfridges but purely for independent, ethical brands, you're sure to find lots of gorgeous gifts, fashion items and more at a range of price points.

I've currently got my eyes on the rings from Kybele Studio and dresses from Zarfie for effortlessley chic summer styling.
