3. Reformation

Reformation’s eco-credentials are extensive, as is their dress selection—including more formal options like ethical evening dresses, prom dresses, and wedding dresses. If you’re in need of a new little (sustainable) black dress, we’re loving the flirty look of the Ezra Cotton Knit Mini dress almost as much as we’re loving the fact that it’s 100% organic cotton.

Why Choose Ethically-Made Dresses?

Ethically-made dresses offer a sustainable and fair alternative to fast fashion. By purchasing these dresses, consumers can support artisans and garment workers who are paid fairly and work in safe conditions. Ethical fashion also promotes sustainability by using eco-friendly materials and reducing waste.

In addition to being environmentally conscious, ethical fashion brands often give back to communities and support fair trade practices. Ethical dresses are often handcrafted and size-inclusive, promoting equity and diversity in the fashion industry.

Choosing to buy ethically-made dresses means supporting woman-owned businesses and promoting slow fashion. By investing in high-quality, timeless pieces, consumers can reduce their environmental impact and create a more fulfilling life for their clothing.

Overall, choosing to buy ethically-made dresses is a conscious decision to support sustainability, fair wages, and ethical practices in the fashion industry.

How We Discovered These Sustainable & Ethical Dress Brands

When looking for sustainable and ethical dress brands, it can be challenging to determine which ones are genuine and which ones are not. To ensure that only the best sustainable dress brands are included, a set of sustainable and ethical fashion criteria was used.


Sustainable materials are fabrics that have a low impact from raw production to end-of-life. Therefore, natural fabric dresses made of organic cotton, hemp fabric, and linen should be the first choice. If they are made of 100% natural fibers, they are compostable.

Silk is a natural fabric, but unless it is peace silk, there may be ethical concerns. Semi-synthetic silk substitutes like closed-loop fabrics from the TENCEL lineup (lyocell fabric, modal fabric, and EcoVero) and Cupro fabric can still provide that flattering drape.

Lastly, recycled synthetic materials made of things like deadstock or plastic waste are also considered. Although they may not be biodegradable, they do put material that already exists to second use.

Certifications such as bluesign®, OEKO-TEX®, and Global Organic Textile Standard (GOTS) are also taken into account.

Supply Chain & Labor Practices

Certified fair trade dresses, USA manufacturing, and small controlled supply chains are some ways companies can demonstrate that they care about treating workers fairly. Third-party certifications like B-Corp also provide reassurance that they are not just greenwashing.

Brand transparency is also examined to see where and how the clothes were made and if the workers are paid fairly and have safe working conditions. Certifications such as B Corporation, SEDEX, fair trade, and Ethical Trading Initiative (ETI) are also considered.

Green Business Practices

Sustainable practices that reduce carbon footprint, carbon offset, product recycling programs, low waste packaging, and slow, sustainable manufacturing are all factors that are taken into account.


Inclusivity is also an important consideration. Sustainable plus-size clothing options that promote diversity and a healthy body image are sought after. Companies that do not exclude body types or sizes are preferred.

Community & Charitable Giving

Brands that give back through charitable endeavors or cultivate an empowered, involved community of wearers are also favored.

Final Thoughts On Ethical & Sustainable Dresses

By wearing a sustainable dress, individuals can model the world they want to live in. Not only do these sustainable and ethical dresses help individuals look good, but they also make them feel good. However, using what one has, borrowing, renting, or thrifting online or at a local thrift store is always more sustainable.
