I’m not going to lie: One of my favorite things about sundresses and house dresses is the lack of decision-making involved. You don’t have to find two pieces that match—you can just throw on a dress with some sandals or heels and look cute without really trying.

So, if you’re looking for eco-friendly, ethically made sundresses you can wear to the park or just your patio, we’ve rounded up the best brands and boutiques for you. But first, here’s an overview of what you should look for while you’re shopping for casual dresses:

Natural fabrics: Most of these brands use fabrics like organic cotton, hemp, linen, and Tencel. Breathable fabrics like these are best if there’s a chance you might break a sweat in your dress. Go for certified organic whenever you can, especially with cotton.

Artisan made: Sundresses give us so much opportunity to play around with colorful prints and patterns. Many of the dresses below are handcrafted by artisans around the globe using traditional techniques that have been passed down through generations, such as block printing.

Nontoxic dyes: Since there’s often a lot of rich colors involved (and again, you might get a little sweaty this summer!) you want to go for nontoxic, biodegradable dyes whenever possible. Otherwise, all of those toxic chemicals can end up in our waterways, our soil, and seep through our skin into our bodies.

Eco-conscious processes: There’s a lot that goes into making just one sundress: growing, shipping, and processing the fabric; dyeing, cutting, sewing the piece; and of course, finishing it and sending it to you—water, CO2, and other non-renewable resources are all used to do that. The brands below seek to decrease their footprint wherever possible, whether it’s making their pieces to order, which cuts down on waste, using recycled fibers, or offsetting the carbon footprint of shipping your dress to you.
