T-shirts are the ultimate wardrobe staple. This versatile and layerable basic has a place in every wardrobe, but if you’re looking for more sustainable tees, where do you even start?

If we had to crown a single item of clothing as the best basic, it would be the versatile and ubiquitous t-shirt. Whether paired with jeans or worn under a jumpsuit or slip dress, t-shirts will see you through all outfits, seasons and styles. They make a great starting point for both giving your basics an ethical overhaul and for curating a capsule wardrobe.

Most of us will throw our t-shirt on in the morning without a thought about its origins. But as conscious consumers, we need to ask questions like: who made my tee? Were they paid a living wage? And is this item made from lower-impact fabric?

With that in mind, we’ve scoured the planet for more sustainable and ethical t-shirts and rounded up our top brands that meet our rating criteria to be classified as “Good” or “Great” overall.

It’s a long list, so we’ve organised it by country first. Don’t forget you can also search for brands in any category on the Good On You brand directory, where we’ve rated thousands of fashion brands. Let’s go.
