The Most Beautiful Eco-Friendly and Ethical Dresses for Cocktail Parties, Weddings, and Prom

An Instagram fan recently asked me if I knew where to buy ethically-made dresses that she could wear to weddings this summer. What a great question! Shockingly, I hadn’t written about this before. Maybe because the choices were so limited.

But there is good news, fashion lovers: Once I poked around amongst my stable of favorite sustainable and ethical designers, I found hundreds of beautiful dresses. I narrowed it down by only including boutiques or brand websites that have at least three pretty cocktail or formal dresses for you to choose from.

And in a happy side note, I also found some plus sizes, and lots of models of color! So we’re getting much more diversity than when I started doing editorial roundups just a few years ago.

So pour yourself a glass of champagne. We’re going shopping.


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!)

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.


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.

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!


Renting your cocktail dress is also super sustainable, budget-friendly, and fun. 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.

I feel like this is enough to get you started. But if I’m missing any of your personal favorite places to get cute cocktail dresses, please let me know in the comments!
