Girl in one piece standing in ocean for best sustainable swimwear brands

Whether you live somewhere with four seasons or you’re a beach-goer year round, everyone loves breaking out their swimsuit for some much-needed sun. I’m a fan of both swimwear and sustainability. That’s the inspiration for this article about my 14 favorite sustainable swimwear brands.

I’ve worked in the fashion industry for quite a few years, including at a swimwear company where I learned about swimwear products and the sustainability efforts (or lack thereof) surrounding the swimwear industry. There are many poor practices throughout fashion production, but the companies below are rewriting what it means to be a sustainable swimwear brand. Let’s get into it.

Note from Hailey: We all need a little makeover sometimes. This article was originally published in April 2021 and has been updated and revamped for accuracy and consistency.

What Is Sustainable Swimwear?

If you’re new to sustainability, let me briefly explain what sustainable swimwear is. If you want to head straight to sustainable swimwear brands, click here.

Sustainability consists of various socially and ethically conscious practices. Sustainability can surround a number of areas from production, fabric content, labor rights, transportation, and much more.

Sustainable swimwear brands have their own individual practices which I will touch on below. However, it is important to note that no brand is perfect. Sustainability is evolving, brands are finally starting to realize it’s important to both consumers and the environment. As a result, sustainable practices take a lot of trial and error along with money which is why many brands are taking baby steps whether that’s making all packaging recyclable/reusable or creating products out of waste like plastic bottles.

Now that we talked a little bit about what sustainability is, let’s dive into these amazing sustainable swimwear brands.

Peony Swimwear

Found by designer Becky Morton, Peony is an Australian label. This brand one of the first-ever sustainable luxury swimwear brands. The Peony style is that of an effortless, coastal breeze, with a focus on neutrals and soft textures. 

The Product
All Peony creates its swimwear with fabrics developed in-house. The textured swim pieces are made from 100% recycled plastic bottles, while the printed swimwear styles are made from 100% regenerated nylon fiber which consists of nylon waste otherwise polluting the earth, like fishing nets, fabric scraps, and more.

The Packaging

The Production
Peony works closely with suppliers who hold internationally recognized certifications. Unlike some other sustainable swimwear brands, all of Peony’s digitally prints their fabrics rather than screen printing. By using digital printing, the brand can perform shorter fabric runs and therefore reduce its fabric waste.
