Check out our curation of plus size sustainable clothing and undergarment brands that are making eco-friendly clothing more accessible.
In an ideal world, we wouldn’t still be attaching a “plus-sized” label on certain garments or differentiating them from the “regular sized”. Especially since the average American woman wears clothing marked between sizes 16–18. But in order for that ideal world to be fully realized, inclusive sizing must be part of the conversation.
The fashion industry has a long way to go when it comes to giving individuals of all shapes and sizes equal access to clothing that lets them express their personal style, no matter the body type or budget. However, some brands are working their way there by extending their offerings to represent a wider size range that’s not only stylish but also sustainable.
From brands that are redefining sizing to labels that are tossing out the size chart altogether in favor of a size-agnostic, made-to-measure model, we found 17 plus-size sustainable clothing brands that are paving the future of what stylish, size-inclusive fashion looks like in more ways than one.
Discover a selection of casual wear, going-out dresses, intimates, swimwear, denim and so much more that carry clothing up to at least size 4XL, with many extending their range far beyond.

Denim jeans are those wardrobe mainstays that are in it for the long haul, you have to try a couple of them out before you find the perfect fit. But what if we told you that you could skip the exhausting process of trials altogether, and have the right pair made to fit your exact proportions and delivered to your doorstep? The denim makers at unspun make this possible by creating custom-made jeans that are not only designed by you but crafted to fit you like a glove.
Using a made-to-order model, the brand allows you to take a 3D scan of your body from your phone within the comfort of your own home and uses that scan to deliver you the best-fitting jeans that are completely unique to you.

We love it when slow fashion brands defy the system and bend the rules to create their own path. And Sotela is one such brand that has done away with the conventional size chart to create its own unique sizing chart, where you can be anywhere between a size 0 to a size 10.
Thoughtfully designed sustainable clothing that has a practical approach to our ever-changing bodies, most of Sotela’s styles are anti-fit, wrap styles, and elasticated at the waist, so it can accommodate natural weight fluctuations and let you wear the item for years to come.

4. Universal Standard
A brand that’s redefining the size chart by offering styles that go from US 00–40, the irony that it’s aptly named “Universal Standard” isn’t lost on us. Universal Standard says that the average American woman typically wears a size 18–20, so the brand took it upon itself to realistically list that size as “Medium” in their charts.
Whether it’s denim jeans, athleisure, cool casuals, intimates, and workwear, you can find everything your heart desires to create the wardrobe of your dreams. Using materials like Peruvian cotton, stretch linen, Italian wool, and French satin, the brand creates high-quality pieces in timeless styles.
Size range: custom sizing that’s the equivalent of US 00–40

(Girlfriend also has loungewear made from recycled cotton + organic cotton.)
Size range: XXS–6XL
7. Big Bud Press
A genderless line of ethically produced casual clothing, Big Bud Press goes the extra mile to ensure you get the right fit by offering an extensive sizing chart that’s categorized and grouped by all the styles they offer.
We love that they’ve gone on to define how every style is expected to fit because our bodies are so unique, the sizes we wear on tops and bottoms alone can differ. Not to mention the way knits and wovens fit can also differ in sizing.
Big Bud Press has you covered if you’re in the market for a new jumpsuit, top, work pants, or even some underwear.
Size range: XXS–7XL
A brand that’s big on offering unparalleled comfort, Miakoda is your place to find the coziest intimates and loungewear pieces made entirely from plant-based materials like organic cotton, soy, and modal lyocell.

P.S. It’s all about the thoughtful little details for us, like their Sal Tank that comes with no labels at the back so it can be worn backward for a higher neckline in the front.
Size range: XXS–6XL
Sculpting swimwear that feels like a hug, Londre creates flattering styles made for adventures in and out of the water. Made from recycled plastic bottles that have been accumulated from beach cleanup projects, the brand claims to use a minimum of six recycled plastic bottles in every swimsuit.
As a long underserved size group in the swimwear space, it’s nice to see brands like Londre fill that gap and offer stylish pieces for sizes that range from XS to 5XL.
We love that Londre offers a recycling program for their worn-out suits so they can be rejuvenated into new materials and that customers can have their suits repaired within the first year of purchase.

All of their swimwear is made using recycled polyester that comes from discarded plastic bottles and fishing nets sourced from ECONYL®.
