Who doesn’t love getting dressed up? Wedding season is here, which means it’s time to doll up and celebrate the lovebirds in your life. As you choose your perfect outfit, it’s important not to sacrifice comfort for style. A synthetic dress that irritates your skin—or worse, gives you a rash—can distract you from fully enjoying the event. 

So it’s important that your fancy dress is made with safe, natural materials, and without harmful dyes and finishes. You wouldn’t want to break out in hives right before photo time!

Certain textiles, such as cotton, can be treated with formaldehyde to make them more wrinkle-resistant and might cause allergic reactions in people with sensitivities. Plus, many formal dresses are made with synthetic fabrics dyed with suspected carcinogenic azo dyes, which can negatively impact human health. Other chemicals like BPA, PFAS, and phthalates in clothing could even affect our hormonal systems.

But the good news is you can look chic and elegant at your next event without compromising your health or inflaming your sensitive skin. Once upon a time, only cotton shifts were available in the sensitive-skin-friendly and sustainable version. But now, you can find beautiful sustainable cocktail dresses made by health-conscious brands. So if you’re searching for a stunning dress to wear to an event this spring or summer, look no further. We’ve compiled a list of non-toxic and sustainable-conscious brands with beautiful cocktail dresses for the 2024 wedding and event season.

What to Look For in an Ethical and Sustainable Cocktail Dress

Natural fibers: You’ll find that many cocktail dresses are made out of synthetic materials, but most can’t compare to the deluxe feel of natural fiber. Plus, natural fibers are a safer bet for your skin. We recommend you consider dresses made out of organic and non-toxic silk, linen, wool, traceable cashmere, or traceable cotton. For the sake of the environment, avoid sequins if you can, and opt for embellishments made of glass beads and natural-fiber embroidery.

Nontoxic dyes: Since there are often a lot of rich colors involved (and you might get a little sweaty on the dance floor this summer!) you want to go for nontoxic, biodegradable dyes whenever possible. Otherwise, all of those toxic chemicals can seep through your skin into your body, especially when you sweat. To know if a material is non-toxic, look for the labels like Oeko-tex and bluesign. You can also look for GOTS, but we recommend only shopping for this certification combined with Oeko-Tex or bluesign to be safe. A great eco-friendly and safe option is plant-based dyes, which are derived from natural sources and used by some of the brands we’ve listed below. 

Eco-conscious processes: There’s a lot that goes into making just one dress. The process starts with growing, shipping, and processing the fabric. It then moves on to dyeing, cutting, and sewing the piece. And of course, the finishing touches before sending it to you. Each of these steps use water, CO2, and other non-renewable resources. Consider brands that decrease their footprint wherever possible, whether it’s making their pieces to order, which cuts down on waste, or offsetting the carbon footprint of shipping your dress to you. Numerous brands also offer plastic-free packaging. Double-check that they wrap your item in either reusable, 100% recyclable or biodegradable packaging.

Fair labor and transparency: Cocktail dresses are a great way to showcase and support traditional artisanship, such as embroidery, weaving, beadwork, lace, and more. We recommend you find artisan brands that list information about the workers who sewed the garment, as well as who sourced and spun the material. For larger brands, check for labels, such as Fair Trade and SA8000, which provide some assurance that your dress was manufactured in safe and supportive conditions.

Washable: Check the care instructions before you buy any dress and try to find ones that can be at least hand-washed instead of dry-cleaned. Most cleaners use a colorless, nonflammable liquid solvent called perchloroethylene, which has been classified as likely to be carcinogenic to humans by the Environmental Protection Agency (EPA). When inhaled, even low concentrations of it, it can cause vision problems, respiratory and eye irritation and kidney dysfunction. Some dresses labeled as dry clean only can be hand-washed — here are some tips on avoiding dry cleaning
