Sustainable and Ethical Holiday Party Dresses

Share Post

The most sustainable fashion choice is to re-wear what we already own, swap clothes with or borrow from friends, or to buy vintage and used clothing. But if you are looking to add new items to your wardrobe, consider buying from brands that have more eco-conscious business practices compared to conventional brands. That said, I’ve searched the internet to find you gorgeous party dresses from sustainable and ethical brands.


Buying secondhand is one of the most sustainable fashion decisions you can make. And this secondhand fashion site let’s you check boxes for the occasion, including “wedding guest” and “cocktail.” Perfect!


I love this website more than Rent the Runway because you borrow from real women’s closets, so the options are really interesting and fashion-forward, instead of being cookie cutter and basic. And you can also sort by occasion.

Stella McCartney

On the super high end of the sustainable fashion scene lies Stella McCartney. She goes beyond fur-free to include organic cotton, certified responsible viscose, and regenerated cashmere.

St. Roche

St. Roche works directly with carefully selected manufacturing partners in India and Peru, who are committed to honest and ethical labor practices. They choose the eco-friendly option wherever possible, incorporating GOTS-certified, organically grown, and locally woven cotton, biodegradable Tencel, and sustainably produced Alpaca knitwear in their collections.


Symbology partners with marginalized artisans in developing countries to create handcrafted pieces using traditional fabric techniques like block printing, tie-dye and embroidery. Most of their dresses are made from sustainable viscose, Modal, and cotton.

Laura Theiss

Based in London, Laura Theiss creates contemporary and timeless knitwear collections for women. The bold, yet feminine aesthetic at the core of the brand gives it a modern edge. Many of Laura Theiss’ dresses are made from 100% cotton.


Made in Barcelona of natural fabrics, this brand knows how to bring out just enough sexy.


Founded by an Argentinian woman, Amur’s name comes from the acronym, A Mindful Use of Resources. They use sustainable materials with vivid prints and sharp tailoring and everything is created in NYC.

Mara Hoffman

I love the direction that Mara Hoffman has gone in the past couple of years. Not only are her pieces now sustainably made, they are oh so chic, while still retaining fun, bright colors. Absolutely perfect for both a city and barn summer wedding. (Bonus for my plus size readers: Mara Has extended sizes in some of these dresses!)

Studio One Eighty Nine

Studio One Eighty Nine, co-founded by Rosario Dawson and Abrima Erwiah, is a made-in Africa fashion lifestyle brand and social enterprise. Headquartered in Ghana, West Africa and the U.S., with a store in NYC and Accra, Ghana, they work with artisanal communities that specialize in various traditional craftsmanship techniques including natural plant-based dye indigo, hand-batik, kente weaving and more.


Roopa’s pieces are designed in the US and ethically made by hand in Nepal. They use fabrics and colors that are inspired by culture and use traditional artisan handwork like patching, layering, and beading.
