Living in the Chicago area, I daydream about finally getting to break out any clothing that isn’t a sweater for about 6 months of the year — so when it’s finally that first day of spring that I can break out my sustainable dresses, I’m a happy camper.
It isn’t that day quite yet here, but that hasn’t kept me from already researching some go-to conscious brands with stunning eco and ethical dresses.
Using materials like organic cotton and Tencel and manufacturing locally or using fair trade practices, the sustainable dress brands in this guide will fit the bill for nearly any upcoming occasion. If you’re looking for exclusively formal dresses, check out my guide to ethical formal dresses here.
Note that this guide includes partners and affiliates. As always, I only include brands I truly love and meet high standards for ethics, sustainability, and aesthetics. Thanks for your support! [Cover image is from Valani]

Valani’s vegan dresses are made from banana fabric — a fiber created from banana stems discarded by the agricultural banana industry — or a hemp/Tencel blend. Both fabrics are breathable, biodegradable, and of course, beautiful!
