We’ve reviewed dozens of summer dresses from sustainable brands — these are our top fair trade and ethical dress selections for comfort, style, fit, and across a range of price points and size options.
As the days get longer and warmer, we’re dreaming of flowy summer dresses and long afternoons spent at the farmer’s market. While not every day can be as luxurious as a Saturday afternoon, we can still sport some of our favorite sundresses without sacrificing our values.
These 10 sustainable brands prioritize fair trade standards and practice ethical manufacturing through the use of deadstock fabrics or organic cotton for their summer dress collections. Many brands also have give-back initiatives that help empower the workers who create their garments. These dresses feel good to wear because they are good.
Our criteria:
- ETHICAL PRACTICES | These summer dresses are made by sustainable brands that adhere to ethical and responsible labor practices, ensuring their employees receive fair wages and have safe working environments. We’ve also included dress brands that give back to their communities and prioritize size inclusivity in their offerings.
- ECO-FRIENDLY/SUSTAINABLE | Each of these summer dress collections is made by a brand that practices sustainability throughout their manufacturing process, including using all natural and organic materials, low-impact processes, and recycled/upcycled materials in their dresses where possible.
- DESIGN | From flowy sundresses to chic and formfitting cocktail attire, we’ve compiled a roundup of dress designs for every possible occasion and need.
- INCLUSIVITY | While sustainable fashion can be pricey and fashion is often limiting when it comes to size ranges, we’ve made an effort to include something for everyone on this list.
