Guide to the best brands for buying ethically made underwear, including period underwear and sexy lingerie options

Underwear is a staple in everyone’s wardrobe, but do you know yours might be doing more harm than good to you and your planet? 

Well, we need to change our underwear every six to nine months, so many of us often look for quantity over quality when buying a new one.

Lycra, lace, nylon, and polyester are some of the synthetic materials the underwear is manufactured from.

Depending on how sensitive you are to a particular fabric; these synthetic materials are not great for the delicate area.

Buying Guide: What to look out for when buying Sustainable Underwear

Opt for sustainably sourced fabric 

Looking for what materials your underwear is made from is important to make a more sustainable purchase.

That means you should opt for certified organic cotton, sustainably sourced viscose such as Tencel or Lyocell, etc. 

Avoid virgin polyester 

Most of the underwear contains synthetic materials, so it is best to avoid virgin nylon and polyester to reduce your environmental impact.

Look for a brand that uses recycled materials to create underwear. 

Look out for harmful chemicals 

Underwear is an intimate garment, so it is particularly important that it is free from harmful chemicals.

Look for OEKO-TEX certified products and naturally dyed materials. 

Zero waste 

The fast-fashion manufacturing process wastes a lot of textiles that end up in landfills.

This is why zero waste fashion is so important as it means the brand either doesn’t produce any waste or that it uses the waste to create more products (called circular fashion).

Sustainable underwear brands use leftover material, as well as repurposed deadstock to manufacture the products reducing waste.

Short FAQ about Sustainable Underwear

1. What does sustainable underwear mean?

For something to be sustainable, it needs to be made in a way that has the least negative effect on the planet. To do this, it should be made in factories that do not create harmful chemicals. Sustainable underwear should also be made using responsibly sourced materials, such as organic cotton or recycled materials. If your lingerie is made with sustainable materials, it should last longer, therefore meaning you will add less waste to landfills.

2. What type of underwear is bad for the environment?

Anything cheaply made is bad for the environment as it is less likely to hold up for a longer period of time and will thus wind up in a landfill sooner. You should also avoid underwear made using polyester, unnatural dyes, or non-organic cotton.

3. Is using bamboo sustainable?

Yes, absolutely! Bamboo is one of the most sustainable materials out there. Bamboo plants are incredibly fast-growing and do not require fertilizers.
