Yes Friends is a fashion brand that pays excellent wages to workers in Vietnam and and India (to help end modern slavery) then passes the savings onto you. Wanting to end the risk of modern slavery (the 2nd highest risk is in the fashion trade), the brand was launched so that you could ‘buy an organic t-shirt for the price of a pint’. At the proper scale, you can buy ethically without much added expense. Avoiding toxic chemicals, most dyes are eco-friendly.
Organic cotton is better for the planet, wildlife and your skin. But also this fabric can be laundered safely in washing machines, without releasing microplastics into the ocean. Donate or recycle unwanted t-shirts, then invest in just a few organic basic t-shirts, that will last you years. Launder synthetic fibres (like polyester) in a microplastic catcher).
