Underwear is a very personal subject, given that you’re wearing it close to your skin every single day, it has to fit well and lift your confidence while being comfortable at the same time. Underwear shapes, support and outline your silhouette. Even the most beautiful outfit will be less lustrous if you’re wearing ill-fitting underwear.
With the rise of sustainable fashion brands, there are still a limited number of sustainable swimwear and ethical underwear options to choose from. This may very well have to do with the fabrics used for lingerie and swimwear as the only way to achieve stretch is by adding synthetic and plastic fibres to the fabric, and plastic is not exactly the most eco-friendly material.
We’re looking forward to seeing more sustainable underwear brands over the next few years, specifically brands that provide shape and support where it matters most. See the list below for some of our favourite ethical underwear brands.

If you’re looking for underwear that provides the feel of more traditional products then Everlane comes pretty close and is still made more ethically than your average high-street bra.
Fabrics Used for Ethical Underwear
When it comes to constructing sustainable and ethical underwear you generally have a wider choice of fabric than sustainable swimwear for example. But even though underwear can be made from organic cotton, bamboo, hemp and recycled nylon or plastic there will still be a percentage of plastic fibres within the fabric.
Plastic fibres such as elastane or nylon are needed to give the material a bit of stretch. Without the stretch, it’s unlikely that your underwear will be super comfortable or stay up for that matter. This means that you need to be mindful when you wash even ethical underwear as it will still shed microplastics into the environment.
You can reduce the microplastics that enter the water system during the washing process by using a Filtrol or a Guppyfriend bag.
