27 Ethical & Sustainable Summer Dress Brands

Sustainable summer dresses have come a long way from those scratchy shapeless sacks. I've rounded up 27 of the most stylish ethical and sustainable clothing brands making comfortable, easy-to-wear dresses that are versatile enough to wear to picnics in the park, cocktail parties, and even weddings and other formal events. I own pieces from the first 6 brands; they comprise most of my summer wardrobe.

Most are mid-range brands. A couple are on the luxury end. I note whenever the labels have a decent sales section or have pieces available to rent on Rent the Runway. Most of these ethical clothing brands are based in the US, with a few from the UK and Canada.

The most sustainable thing you can do is avoid the overconsumption of clothing. Buy fewer but better-constructed garments that will last, which these brands do well. Don't forget you can always search for summer dresses secondhand on resale apps

You'll often find me wearing Faithfull dresses and tops in the warmer seasons because they're so easy to wear and take care of. They're my go-to brand for building a romantic summer wardrobe.

2. Christy Dawn

best fair trade dressesPin

When I discovered Christy Dawn a few years ago through the ethical fashion scene, they were making dresses from deadstock fabric, fabric left over from bigger fashion houses. They still do for their Deadstock Collection. To expand the brand while still remaining sustainable, they launched a "farm-to-closet" initiative in southern India, working with traditional farmers and craftspeople to nourish a depleted plot of land back to health, and sowing their own cotton with regenerative techniques that honor Mother Earth.

Based in California, they work with talented dressmakers in LA and India to make garments that last. I own a couple of Christy Dawn dresses, and I expect to keep wearing them for decades to come.

3. Dôen

Founded by women from Santa Barbara, Dôen is inspired by nostalgia for California of decades past. Their feminine, romantic dresses are made with care in India with GOTS-certified organic cotton. The summer dresses also come in children's sizes for mothers searching for matching family sets.

Dôen's clothes are timeless. I invested in The Jane Blouse in the color Salt over five years ago. I wear it frequently, and it still looks as good as new.

4. Reformation

Reformation built their own factory in Los Angeles and also works with sustainable factories abroad. Their flirty summer dresses are often seen on celebrities and they have stores in the US, Canada, and the UK. If. you're in the States, Reformation pieces can be rented from Rent the Runway.

I own a few Reformation pieces and recommend avoiding their viscose/rayon garments. They're dry clean-only; they'll shrink in the wash, even under the delicate setting. I also don't have confidence the fabric will hold up in the long run. Instead, choose their linen dresses or pieces made from other natural fibers. (FYI, they make great jeans.)
