If you’re looking to build a planet-friendly closet, one of the smartest staple pieces to invest in are sustainable dresses. Shopping ethically is the key to dismantling the fast fashion industry, which is responsible for more greenhouse gas emissions than the shipping and aviation industries combined.1

Eco-conscious consumers are turning to the “slow fashion” movement, which prioritizes ethically sourced and sustainable materials and working conditions. Sustainable dresses are a crucial piece to include in your capsule wardrobe for their versatility and style, and we’re here to spur your shopping spree with this 2023 guide to the top picks.

Finding Sustainable Fashion: Dresses

The average American buys a new piece of clothing every five days, and 90% of that wardrobe ends up in the trash.2 In order to break this cycle of purchasing and disposing, it’s essential to purchase durable, versatile pieces that can be worn over and over again rather than focusing on quantity and following trends. Dresses are a staple piece in any closet and can fill a variety of gaps in your outfit repertoire. Luckily, there are a plethora of ethical, sustainable brands that offer stylish, timeless dresses at a variety of price points. If you’re looking to reduce your carbon footprint in the fashion department, it’s important to choose brands that are transparent about their manufacturing processes and the materials they use.

Finding beautiful, stylish and sustainable dresses isn’t impossible. These fashion favorites look stunning, and help the planet by reducing the ecological costs of the clothing industry. These favorites can ease your transition from fashion hare to fashion tortoise!

What’s So Important About Eco-Friendly Dresses?

Over 60% of fabric fibers are derived from fossil fuels, meaning they will not decay when 85% of them end up in landfills.5 The fast fashion industry is the Earth’s third largest polluter after food and construction, which is not hard to believe considering the sheer volume of the modern wardrobe multiplied by seven billion people. The only way to fight fast fashion is by slowing down.

Purchasing multifaceted pieces like dresses from ethical companies is a great place to start, and waiting longer to replace them by avoiding the trend vortex is even more powerful. You’ll find peace in the transparency of knowing where your dress came from, and will develop an evergreen, luxuriously simple sense of style while contributing to saving the planet.

What Are Ethical Dresses and Ethical Summer Dresses?

Truly ethical dresses come from companies that are completely transparent about their production processes and use only ethically sourced or recyclable materials. Companies that commit to clear goals and standards, like Everlane’s commitment to aligning with the Paris Agreement or Nu-In’s commitment to veganism, are trustworthy enough to produce pieces with minimal carbon footprint.

Buying ethical clothing is a holistic approach to fashion, because not only does it impact the lives of the people who work to fabricate textiles, but it also reduces the cost to the environment. And, every little bit helps.

Finding Deals on Organic Cotton Summer Dresses and Organic Sundresses

Ethically made, eco-friendly dresses are sometimes more expensive than their fast-fashion counterparts because factory workers are paid fair wages and higher-quality materials are used in production. However, sustainable dresses are worth the investment, especially considering they are designed to be purchased in lower quantities, durable enough to last for years, and timeless in style so they outlast trends. In order to achieve this quality in your wardrobe without breaking the bank, keep an eye out for sales, particularly at the end of the season.

Most sustainable dresses are designed to be relatively trans-seasonal anyway, so you’ll still be able to wear them right away. If you’re still struggling to find affordable eco-friendly dresses, consider buying secondhand or from local sellers in your city. Search for sellers on Etsy or similar online marketplaces who upcycle secondhand clothing. If you’re looking to save and indulge in the occasional trend, consider renting pieces from companies like Rent the Runway or labels with their own garment rental program (like ba&sh, listed below).

We’ve included a list of some honorably mentioned sustainable brands below.

Fast Fashion Facts: Why Buying Sustainable Dresses Can Help the Planet

Some quick facts about fast fashion:

  • 80% of all clothing ends up in a landfill or incinerator6
  • One garbage truck of textiles is landfilled every second1
  • The ratio of tons of water used to tons of fabric produced is 200:16
  • Synthetic fast fashion pieces will become part of our fossil record, meaning archaeologists will discover them even after landfills are consumed by nature5
  • The fashion industry is responsible for 1.2 billion tons of CO2 emissions annually1
  • 0.6% of the price of a garment goes to the factory worker who made it6
  • Producing one cotton shirt creates the same amount of greenhouse gas emissions as driving a car 35 miles6
  • Even landfilling non-synthetic items (which will decay) matters, as it contributes to the emission of methane5
  • The fashion year has subdivided into 52 micro-seasons, meaning new lines are released every week1

The quickest antidote to the monster of fast fashion is simply its opposite: slow fashion. By slowing down our consumption of clothing, we can not only reduce our individual carbon footprint, but also contribute to crucial related causes, such as factory worker rights and animal welfare.

The emergence of ethically transparent, sustainably sourced brands has become something of a revolution, making eco-friendly clothing readily available online and locally at a variety of price points. When stocking your closet for any new season, consider reaching for any of these sustainable dresses… you’ll look great, and be helping the planet.
