Best B Corp Clothing Brands You Need To Know 2024

As many of us know, being more eco-conscious of our shopping habits is more important than ever, but with so many brands out there greenwashing, it can be hard to tell which brands are actually trying to do good for the planet.

Luckily for us, there’s an easy way to spot which brands are really making positive changes, and which ones are all talk, thanks to the B Corp Certification.

If you’re already familiar with what a B Corporation is and are wanting to learn more about brands that have the certification, you’ll find out which brands have it in this guide.

If you’re just learning about what being a B Corp means, we’ll explain the topic so you can be a more eco-conscious shopper.

Let’s dive straight in! 

B Corporations — B Corps for short — are for-profit companies that have been awarded a B Corporation Certification from B Lab. 

The certification takes into account all aspects of the brand and ensures the company is focused not just on making profit, but adhering to strict social and environmental standards.

As a Certified B Corporation, brands must meet these high standards of verified social and environmental performance, transparency, and accountability. 

Brands can be audited at any time and have their status revoked, so if a brand is a B Corp, you can feel confident buying from it.

The fashion industry is known for its often-questionable ethics and environmental impact, so B Corps are a breath of fresh air. They show that clothing can be stylish, high-quality, and produced in a way that benefits both the planet and people.

When buying from a B Corp, you can use the B Lab website to search for the brand you’re considering and check out their credentials and scores yourself before buying.

PAKA integrates traditional craftsmanship with contemporary style through the use of alpaca wool. 

The brand achieved its B Corp status thanks to the choice of natural, biodegradable materials and support for small-scale Peruvian artisans. By employing local weavers, PAKA helps preserve ancient weaving techniques and contributes to the economic stability of these communities that often lose out due to large fast fashion corporations appropriating.

It’s worth highlighting that PAKA isn’t a vegan brand, as it does use wool in all its garments. However, we should mention that the brand does source the wool ethically — hence the B Corp Certification.

In our opinion, tentree is one of the leaders in sustainable fashion due to how they’ve managed to grow while staying true to its original mission.
