Who said saving the planet couldn’t be chic *and* size-inclusive?

Shopping sustainably is hard enough, but throw in the hunt for pieces that actually fit a size 26 body (and beyond) that *don't* compromise on style or ethics, and suddenly you're on what feels like a never-ending fashion treasure hunt – without the treasure. The truth is, plus-size shoppers have long been left out of the sustainable fashion conversation, with most eco-friendly options stopping short at mid-sizing.

What makes a brand sustainable?

While not all brands get it, there are a few labels that recognise sustainability and inclusivity have to go hand in hand, and they're delivering on both fronts. We're talking brands using lower-impact fabrics like organic cotton, deadstock, and recycled fibres, paired with fairer labour practices and transparent supply chains. Others are tackling waste head-on by upcycling vintage finds or designing with circularity in mind, so nothing ends up in landfill before its time.

Even basics aren't being overlooked. Think tights and everyday essentials made to actually last, not rip after a single wear. And for those of us who value comfort just as much as conscious design, there are collections centred around versatile, long-lasting pieces that work across bodies, moods, and moments.

In short: inclusive, sustainable fashion does exist, and it's a lot closer than you might think. Not to mention pretty fabulous, too. Below, find my roundup of some of the very best sustainable and size-inclusive brands around.

Why should you trust me?

As a former curve model turned digital content creator, I've been working in the fashion industry for years now, specialising in plus-size fashion content, so I think it's safe to say I'm something of an expert. I love testing out brands IRL and sharing my finds to inspire other women to live boldly through their clothes, just like I do.

Reformation

Reformation

Size range: 4 – 28
Best for
: Stunning occasionwear

As one of my favourites, Reformation delivers on both style and sustainability. They prioritise lower-impact fabrics such as TENCEL™ lyocell, organic cotton, and recycled materials, while avoiding virgin synthetics wherever possible and giving new life to deadstock fabrics. Whether you're after a signature occasionwear look or an everyday staple, Reformation has curve gals covered thanks to their ‘Extended Sizes’ available in the brand's most popular styles.

Customer review: “Well-made and gorgeous ‘fits and I appreciate their sustainability practices. I feel great wearing Reformation – it is so refreshing to be able to buy sustainable, fashionable clothing in a proportion that fits my frame! You may need to size up if your bust is on the larger side, like mine.”

Lucy & Yak

Lucy & Yak

Size range: 4 – 32
Best for: Colourful everyday wear and cult dungarees

Lucy & Yak has built their cult status on more than just colourful dungarees. They’re committed to using GOTS-certified organic cotton, recycled fabrics, and even offcuts that would otherwise go to waste. Their factories in India are audited for fair working conditions, and they run buy-back and resale initiatives to extend the life of their garments, making them one of the UK’s strongest examples of circular fashion.

Customer review: “I was impressed by the sizing range the quality of the clothes! I’m a curvy girl with about a nine inch difference between my waist and my hips, so nothing ever fits properly and I have never been able to wear dungarees. I took a chance and Lucy & Yak's fit so amazingly! They fit my thighs and hips, and cinch at the waist – something I have not been able to find in ANY of the mainstream stores. I’ve just found my new favourite brand.”

Not to mention, they are also transparent about their production partners and invest in ethical manufacturing practices, proving that scalability and sustainability can coexist. It's worth the international shipping costs, trust me.

Girlfriend Collective

Size range: XXS – 6XL
Best for: Sustainable activewear that actually fits

With inclusive sizing up to 6XL (around a UK 30), they’re showing that sustainability and accessibility can go hand in hand. With UK stockists including M&S, it's now easier than ever to get your hands on their pieces.
