66% Say They’ll Buy Sustainable Fashion. Here’s Why They Don’t

While consumer surveys often reveal that consumers are willing to pay a premium for sustainable products, sustainable fashion consumer behavior in real-world settings tells a different story.

Why Consumers Say They’ll Buy Sustainable Fashion- But Don’t

A Nielsen study reports that 66% of global consumers are willing to pay more for sustainable fashion. That number is even higher in Europe, where 72% of consumers report a similar preference. But there's a problem with that number: it does not match what actually happens when people walk into a store - revealing why people don’t buy sustainable fashion despite stated intent.

A recent study - Experimental evidence on consumers’ willingness to pay in the sustainable fashion industry - published in Nature tells a different story. It reveals a significant gap between what people say and what they do, and the factors that nudge someone to make a different choice.

Let’s explore.

The attitude-behavior gap in Sustainable Fashion

The Nature study analyzed what makes someone actually purchase a sustainable garment and not merely talk about buying. And what the research found is that environmental concern alone is not the key driving factor.

The research identified four key factors that work together to drive real purchases of sustainable fashion:

What Actually Drives Sustainable Fashion Purchases

1. Environmental and social values

People who care about the environment are more likely to buy sustainable fashion. That’s probably too obvious - but values alone do not close the sale even though they set the foundation.

2. Perceived quality

Consumers need to believe the sustainable product is actually of good quality. This means if the product looks cheap, feels cheap, or seems like it will not last, the environmental credentials lose importance. The finding is unambiguous here: People will not buy inferior products, regardless of how green they claim to be.

3. Transparent production costs

When consumers see the higher price; they need to understand why. Is the higher price substantiated by better materials, specialized labor, fair wages or something like excellent craftsmanship? 

If you cannot explain why the products have a premium price, people assume they're being overcharged for a marketing narrative.

The Role of Design, Quality and Trust

Design and aesthetics

This is one of the most understated factors in sustainable fashion, and the Nature study reveals something counterintuitive about it.

The researchers tested three bags. Bag A was a conventional leather product. Bag B was made from recycled leather. Bag C was the most circular of the three, made from shredded leather scraps, and it came in two versions: one with a natural finish that reflected what the material actually was, and one with a glossy coating added on top.

When consumers were asked about sustainable fashion purchase intention, both versions of Bag C scored similarly. But when it came to actual spending, the glossy version saw significantly lower willingness to pay.

This means that while design is important, it needs to be honest about what the product is. Trying to make a recycled or circular material look like a conventional premium product does not increase its perceived value - rather it undermines credibility. The design needs to be consistent with the material's identity, not working against it.

The moment the most sustainable version of the product looked worse, willingness to pay dropped significantly, even among consumers who said they cared about the environment. This means consumers will pay more for sustainability only when conventional product standards are also met. Not instead of them.

The paper concludes that "Sustainable features may only drive consumer interest when other expectations, particularly design and quality, are also met"

Why Sustainability Messaging Alone Fails

Why is there a gap?

So if 66% say they'll pay more, why don't they?

The first factor is greenwashing skepticism, which comes from consumers being disappointed too many times. They've bought products marketed as "eco-friendly" only to discover the claim was exaggerated or unsupported. So, skepticism has now become the default.

Whenever a consumer sees another sustainability claim, the first reaction is: Is this real or marketing?

And then comes doubt about quality. The sustainable fashion category has a perception problem. Many people believe that sustainable fashion means choosing something that looks worse, feels worse, or it will not last. This does not have to be true but perception drives purchase behavior.

The third point is the lack of ethical fashion pricing transparency. Many sustainable brands fail to explain why  their products cost more. While claims like "Ethically made" "Eco-friendly" "Sustainable materials" make good marketing campaigns, these words tell the consumer nothing about what they're paying for.

Consumers also want to know if they are paying for the labor, materials, design, manufacturing time, specialized knowledge, or something else. Without specificity, consumers take the higher price as arbitrary.

How Sustainable Brands Can Convert Intent into Purchase

How do we close this gap?

Brands that successfully convert willing consumers into actual buyers do one thing consistently: they make the invisible, visible. So how do they do it?

They do it by showing their production process, introducing the makers, explaining the materials that go into making the products more sustainable.  These brands also justify the price with specific information without vague promises or claims that are not backed by evidence.

When consumers understand how something is made, who made it, and why it costs what it does, they make an empowered and informed choice.

What this means for sustainable fashion brands

The first lesson is that the future of sustainable fashion does not belong to brands that focus narrowly on environmental messaging. To be successful in this space, brands need to deliver on all four factors: environmental values, perceived quality, transparent pricing, and compelling design.

At Vino Supraja, a Dubai-based contemporary art atelier working at the intersection of craft, culture and sustainable luxury, this understanding informs how we approach design and communication - not as claims, but as visible processes.

The underlying idea is that the consumer is not willing to pay more to buy a "sustainable product." The messaging needs to be more direct, more visible, and more transparent - especially when it comes to ethical fashion pricing transparency and production clarity. People make purchases when they see a product made with care, materials they understand, by people they can identify with. It also needs to look and feel worth owning.
