Say Goodbye to Fast Fashion in 2025

Why does fast fashion persist in 2025, when we know it’s bad for the planet? Well, it’s far too easy. It’s the name brands we all know, it’s the cheap clothes, it’s the quick shipping, and the idea of always being “on trend” that keeps us coming back for more. But clothing waste is taking over. It’s up to us to influence the future of fashion with our purchasing choices.

Fast fashion is convenient, but it comes at too great a cost—to the environment, to garment workers, to the longevity of our wardrobes, and ultimately, to us. We wear cheap, toxic materials on our bodies and create clothing waste that burns toxic emissions into the atmosphere when disposed of.

We really do believe that people want to make better choices, but it’s hard to know where to start. Especially with so many fast fashion brands using influencers and hauls to encourage us to buy more on social media.

We’ve designed this list specifically to help you swap the fast fashion companies we’ve come to rely on for more sustainable alternatives.

If you’re already well on your way to building a more conscious wardrobe, hopefully we can introduce you to a few new sustainable clothing brands that you’ll love!

This guide is a running list of the sustainable clothing brands we swear by, categorized by affordability and purpose, so you can make informed choices and build a wardrobe that aligns with your values and the planet.

1. ThredUp

Why we love it: ThredUp is the largest online thrift store, offering secondhand clothes from thousands of brands. Shopping secondhand extends the life cycle of clothing, reduces textile waste, and keeps perfectly good garments out of landfills.

Is thrifting considered sustainable fashion?

Yes, thrifting is a key aspect of sustainable fashion because it extends the life cycle of clothing, reduces textile waste, and decreases demand for new garment production, which has a high environmental impact. Buying second hand helps divert clothes from landfills and lowers the carbon footprint of fashion consumption. (source: ThredUp)

Where do old clothes end up?

Most old clothes end up in landfills or are incinerated, with only a small percentage being recycled. Many donated clothes are exported to developing countries, where they can overwhelm local markets and contribute to textile waste. Proper recycling and buying secondhand can help mitigate this issue. It’s hard to comprehend just how damaging this can be, so take a look at it here.

2. Nuuly

Why we love it: Instead of buying a dress for a single occasion, rent it from Nuuly. Their subscription model lets you choose six items per month from top brands, making it an affordable and sustainable way to wear high-quality clothing without waste. Nuuly allows us to have fun with our style and keep our warddrobe fresh without contributing to fashion waste.

3. Seaavision

Why we love it: SEAAV creates buttery-soft activewear from recycled plastic bottles. Every SEAAV purchase diverts 1 lb. of ocean-bound plastic from our shorelines, and the comapany donates 1% of profits to coral reef restoration. Plus, it’s female-founded by an incredible young entrepreneur!

4. Girlfriend Collective

Why we love it: With inclusive sizing, ethically sourced materials, and transparency about their supply chain, Girlfriend Collective makes sustainable activewear a norm rather than an exception.

5. Reformation

Why we love it: Reformation combines sustainability with style, using eco-friendly fabrics, responsible production practices, and carbon-neutral shipping to create fashion-forward pieces with a conscience. It’s our favorite brand for city style and those who love to be on-trend without supporting fast fashion practices.

6. Indigo Luna

Why we love it: Indigo Luna handcrafts sustainable, slow-made pieces using plant-based dyes and organic fabrics, creating garments designed to support mindful living both on and off the mat. We discovered this brand while traveling in Indonesia and it’s quickly become our go-to loungewear when we travel!

7. Dippin Daisy's

Why we love it: With ethically produced, size-inclusive swimwear made from recycled materials, Dippin Daisy’s is the one swimwear brand we’ve found that manages to be stylish, affordable, AND eco-conscious. We’ve been living in these swimsuits on Martha’s Vineyard and bringing them along on all of our travels for a few years now, making this one of our very favorite sustainable brands. Plus, Dippin Daisy’s is female founded and run by an incredible team of women.

8. Levitate

Why we love it: Rooted in New England surf and outdoor culture, Levitate produces durable, timeless pieces using sustainable fabrics, perfect for those who embrace coastal living. This brand embodies our New England lifestyle and aesthetic. They even created a sea-wool blend for their sweaters that features 50% recycled wool with oyster shells woven in.

9. Pact

Why we love it: Pact specializes in organic cotton essentials that are soft, breathable, and free from harmful chemicals. Their commitment to GOTS-certified organic fabrics means their pieces are better for both the planet and our health. When it comes to saunas, choosing non-toxic clothing is crucial—many synthetic fabrics release harmful chemicals when exposed to high heat. Pact’s organic cotton is a safe, comfortable choice that lets you fully enjoy the benefits of heat therapy without worrying about toxins.

What is the most toxic fabric?

Polyester is considered one of the most toxic fabrics due to its reliance on petroleum-based synthetic fibers and the chemicals used in its production. It sheds microplastics into waterways when washed and is often treated with toxic dyes and finishing agents. (source: Greenmatch)

What is the least toxic fabric to wear?

Organic cotton is one of the least toxic fabrics because it is grown without synthetic pesticides or fertilizers and is often processed without harmful chemicals. Other safe options include linen, hemp, and Tencel, which are biodegradable and made with minimal chemical input. (source: The Organic Center)
