How To Shop For Ethical, Sustainable Underwear + 12 Top Brands
Underwear is probably not the first thing that comes to mind when you think about sustainable swaps. But like anything else in your closet, your undies have an environmental impact of their own! Here are a few ways to shop for underwear that's a bit easier on the planet, and 12 ethical brands to trust with your intimates.
What it means for underwear to be ethical & sustainable.
Sustainable underwear is typically made with a "slow fashion" mentality—meaning it's thoughtfully created to have a low environmental impact along all parts of its life cycle:
- Starting with materials, undergarments made from natural materials like cotton or hemp tend to be more sustainable than those made from petroleum-derived synthetics like polyester or nylon. Sustainable stylist Cassandra Dittmer adds that natural materials tend to be more breathable and less likely to cause irritation—especially important when you're choosing what to wear down there.
- Moving on to production, ethical undies are made in factories that take care of employees (physically and monetarily) and don't contribute to the human rights issues in the fashion industry. They are crafted using low-impact treatments like natural dyes whenever possible.
- And finally, they are durable enough to keep end-users (that's you!) comfortable for years to come. Since things like bras and underwear shouldn't be re-worn secondhand, ethical and sustainable underwear will also ideally be recyclable or compostable.
Things to look for.
With this in mind, here are four things to consider when you're looking for ethical underwear you can feel great about wearing:
- Material: "All-natural materials are always best," says Jessica Kelly, founder of sustainable sourcing platform THR3EFOLD. She adds that underwear made from recycled materials like plastic bottles is also considered more sustainable. However, it will still shed microplastics in the laundry (important to consider since we wash them so much) and won't be compostable.
- Labels: Look for underwear made from organically grown materials, especially if you have sensitive skin that's easily irritated, Dittmer says. She points to the Global Organic Textile Standard (GOTS) as one label to look for to ensure your panties are pesticide-free.
- Company mission & values: Dittmer adds that you'll want to take that extra moment to read a company's "About" page before investing in their pieces. This should tell you more about how they run their business and treat their employees. Bonus if they offset their emissions, power their factory on renewable energy, or reduce their environmental impact in another verifiable way. Think you're being greenwashed? This guide will help you decide if a company's claims are legit.
- Recyclability: "No one is going to buy used old underwear, so it often gets thrown away at the end of its life, adding to the textile waste in landfills," Kelly says. Thankfully, it's becoming more common for brands to accept used garments for recycling or downcycling, so that's a good option to look out for. If the entire garment (down to the waistband) is made from natural materials, it may also be compostable—meaning it will break down in the environment without a trace within a relatively short time period.
Each of the following brands fills at least one of these sustainability buckets. (We'll give you a quick summary of its eco-perks up top.) You'll find a number of different styles, sizes, categories, and price points listed to help you find your perfect fit.
