11 Sustainable Basics Brands That Basically Grows On Trees

Amber McDaniel

There’s nothing #basic about sustainable basics clothing that reduces our impact on the world. 

Between organic fabrics, ethical manufacturing, and future-proofing brands, everyday essentials can be much more than your go-to comfy clothes.

Finding good quality basics can be difficult with all the fast fashion brands running a muck, which is why we compiled a list for you, so you can focus on the fundamentals. 

Everything we recommend to you on Sustainable Jungle is independently researched and we ask all brands to confirm their claims. To avoid waste, we test products on an as needed basis. This post contains affiliate links. If you buy something through our links, we may earn a small commission. Learn more about why we do this here.

The Best Sustainable Basic Clothing That’s Anything But #Basic

Keeping it local, Harvest & Mill is one of the few brands offering ethical basics made in the USA. 

For tees that won’t won’t break the bank, you won’t be barking up the wrong tree with tentree—though there will be plenty of bark since each item you order will help plant ten trees.

Pact helps even the old clothes you’re replacing make an impact thanks to their Give Back Box, which lets you donate any brand of clothes (basics to ballgowns) to those in need.

Basic(ally), you can head to the end of the article to see why these sustainable basics brands made the list.

How We Chose The Best Eco-Friendly Basics

Better-for-earth basics start with considering the following sustainable fashion criteria.


Going au natural is the most basic way to dress, but natural, sustainable fabrics are a close second.

Organic cotton, hemp, wool, and linen are a good choice for us and our planet. Semi-synthetics, like lyocell fabric, are close seconds.

Stretchy, breathable fabrics often require synthetics like polyester and nylon, but these are best when kept to a minimum or are made from recycled materials.

Supply chain & labor practices: 

Uncomfortable and ill-fitting clothing has nothing on greenwashing.

Going beyond basic to transparently share manufacturing details, factory locations, worker pay, and a Code of Conduct is what we look for in ethical brands. 

Third-party certifications provide extra assurance. 

Carbon commitments & green practices: 

The most sustainable basic clothing are those with an impact compensated by carbon offset programs or using renewable energy and other practices that reduce water, energy, and chemical use.

Plastic-free shipping, programs to reduce or reuse waste, and ensuring manufacturing processes don’t pollute the environment are also important.


Basics should be for all bodies, so inclusive sizing is essential, as is using models that represent all the bodies their clothes are made for.

Community & charitable giving: 

Brands that give back—through money or product donations, volunteering, or a brand using its platform for good—make that oversized tee feel extra cozy.

Final Thoughts On Sustainable Basics Clothing Brands

Good quality basics and slow fashion go hand in hand.

You can feel good knowing that your everyday essentials are made in a way that minimizes environmental impact.

But before you shop for eco-friendly basics, check out a second hand store for your staples.
