Best Sustainable Underwear UK: Ethically Delicate

Dresses, jumpers, shoes… Switching to slow fashion is going pretty smoothly (go, you!), but isn’t there something you’re forgetting?

The best sustainable underwear in the UK will allow you to add another ethical and eco-friendly layer to your outfits.

Why choose sustainable underwear instead of fast fashion?

Some fast fashion underwear

Paying £3 for some fast fashion underwear might feel tempting since it’s going to be hidden underneath your clothes for most of the day. 

However, there are both health and ethical concerns that you should consider:

  • Most fast fashion underwear consists of synthetic fabrics like polyester, which tend to trap heat and moisture, messing up with vaginal health. This isn’t to say that you can’t ever wear polyester underwear every once in a while, but rather that it’d be safer to stick to natural fabrics most of the time
  • While natural cotton should be a safer alternative, fast fashion companies often employ pesticides and chemicals to speed up the growing process: not exactly what you should wear down there! 
  • As well as the material itself, the main issue with fast fashion underwear is that it frequently involves toxic chemicals and dyes. This is awful news in general, but even more so for clothes that cover your most delicate body parts
  • Plus, the usual problems with fast fashion still apply: this underwear is mainly produced by exploited garment workers relying on materials and practices that are harmful to the environment 

Instead, the best sustainable underwear involves natural fabrics or recycled materials, safe dyes, and fairtrade production methods.
