Size Inclusive Sustainable Fashion Brands

This guide to size-inclusive sustainable fashion brands is just the start of my research! In this article, my focus is on identifying brands that serve women of various shapes and sizes, particularly those that embrace body positivity and ethical practices.

I believe that sustainable fashion should be accessible to everyone. Yet I hear lots of women tell me that they can’t find good quality sustainable pieces easily, and that they need to compromise on quality or style or their values to get clothes that fit.

Plus-sized brands – fashion that’s size-inclusive

Many of the brands listed below are leading the way by offering stylish and eco-conscious options for plus-sized gorgeous women. Just because you’re a curvy fashionista doesn’t mean you are limited to fast-fashion.  If you have the luxury of being able to invest in sustainable brands with slightly higher price points, then this list of brands is for you. 

If you can’t afford these brands full price, perhaps look out for them at clothes swaps and online preloved clothes apps and websites. If its possible go into stores that sell the pieces. Try things on and get an idea about the fit so you can purchase preloved with confidence.

Size-Inclusive Sustainable Fashion Brands for Curvy Women

Below, you’ll discover a list of plus-sized brands that cater to a diverse range of style preferences. Please note that, apart from Reformation, I haven’t personally tried, tested, or vetted any of these brands independently..  If you have any experience buying from these brands as a plus-sized babe, please let me know!

Plus-Sized Fashion and Size-Inclusive Ranges:

I hope this size-inclusive sustainable fashion brands guide has helped. I’ve carefully compiled this list of brands that celebrate body positivity and embrace sustainability. 

From elevated basics, and everyday clothing to swimwear and denim, these brands offer a small section of stylish options for plus-sized individuals, without compromising on ethical practices.

Sadly the fashion industry needs to be more size inclusive, this is not just limited to ethical and sustainable fashion.

Plus-sized fashion that’s affordable

If you’re seeking size-inclusive and sustainable clothes, but have a limited budget you may feel that there are no other options other than purchasing from ultra-fast fashion brands.  I always recommend looking for those high-street and sustainable brands you can’t afford full-price on secondhand thrift apps online.

Popular brands I see being sold for less on preloved sites

Whilst Nobody’s Child seemed like a good alternative to fast fashion, I have my doubts about the business model and ethics of this brand. However, Nobody’s child has around 43 options on their website that have extended sizes, they go up a size UK size 24. I often see lots of people listing their clothes from this brand on Vinted and Depop, so it’s worth checking them out.

Ganni, whilst self endorsed as “not a sustainable brand” offer long-lasting quality clothing. It’s easy to find Ganni items on preloved sites. I have spotted that Ganni now have some styles that go up to a size UK 24. I have many preloved Ganni pieces and I can vouch for the quality, material is great and it lasts.

Buying preloved is the way to go

I rarely buy anything at full price myself these days, I always find most things preloved, however, I’m not plus-sized. It’s hard to truly understand the firsthand frustration of seeking out clothes I enjoy that also fit well in terms of size, shape, colour, and on a constrained budget.  I am curvy and petite (under 5 foot 4) so I can relate to the frustration of finding clothes that fit.

One tip I will share is that setting up alerts on eBay has been very useful for pieces that myself or my clients have been OK to wait for. For example, if you ‘re searching for a navy blue blazer in organic cotton size XXXL, you can create a saved search on eBay. When an item becomes available that matches your keywords you’ll get a notification.

Purchase consciously and slowly 

If affordability and style lead you to purchase clothes from ultra-fast fashion brands, and you’re content with the quality, consider opting for preloved pieces. However, it’s important to note that many fast fashion brands produce hundreds to thousands of garments daily, leading to a significant portion of these ending up in landfills.

Whilst I know this isn’t a solution, opting for preloved is a way to do your bit and help divert clothing from ending up in the ground. By buying preloved pieces, giving them care, and handling fixes and upcycling as needed, you can lead a more sustainable lifestyle without the high costs.

The sustainable fashion space still has a lot of catching up to do. I will continue researching and gathering more brands to add to this list. Meanwhile, don’t hesitate to inform me about any additional brands that you believe should be included in this list.
