If you’re here, you’ve probably been hearing about the increasing outrage at fast fashion brands like Shein and Zara. This blog will explain exactly why fast fashion is unsustainable and how slow fashion is an important part of the solution!
The fast fashion industry thrives of the way our current society is formed around convenience, microtrends, and easy accessibility. But buying new clothes for the price of a coffee every other week comes at a high environmental and social cost. Many studies have proven how they have generated excessive waste, pollution, and worker exploitation, and are a significant driver of global warming.
With this growing awareness, many are turning to slow fashion as an alternative—a more thoughtful, sustainable, and ethical way to build your wardrobe. If you’re wondering exactly what that means, this blog will explain why slow fashion matters and how you can adopt it in your own life.
Going against your normal habits can seem overwhelming and difficult – “Doesn’t sustainable = more expensive?”. Don’t worry, it’s easy to start and once you get the hang of it you’ll wonder how you ever lived any other way.
Why is fast fashion unsustainable?
So what is fast fashion? It refers to the fast production of cheap clothing, that is made to follow the latest microtrend instead of becoming a lasting part of your wardrobe. (warning: rant incoming)
Fast fashion brands release an insane amount of new products almost every day, made at very low cost and sold at low prices. To offer low prices and quick production cycles, it is obvious that the quality of the clothing is abysmal, as is the impact on the environment and the workers that have to make the clothes.
By offering very low prices, people buy lots of these clothes regularly. They usually don’t last longer than a few months, but by then there are newer trendy items that are just as cheap, so why not just buy more, right? And so society has entered a vicious cycle of overconsumption and staggering amounts of textile waste ending up in landfill.
A fact that illustrates this is that since 2000, people buy twice as many clothes per year, but wear them far less often- the average number of times an item was worn decreased by 36%.1 All those impulse purchases based off microtrends and discounts lead to an estimated 50-80% of clothes in people’s wardrobes being unworn.2
What is the environmental impact of fast fashion?
To start, the fashion industry accounts for 8.1% of global greenhouse gas emissions.3 That’s higher than the emissions of air travel and maritime travel combined, by the way.1
Globally, we consume 62 million tonnes of clothes per year. By 2030, this is expected to reach 102 million tonnes.3 On the flip side, the fashion industry procedures 92 tonnes of textile waste per year – this amounts to 1 garbage truck full of clothes being dumped in landfill or incineration every second.1 87% of fibre used for clothing is either landfilled or incinerated, with less than 1% being recycled into new clothes.3 That is what happens in a model that prioritises quick and cheap clothes – it generates more waste than what is actually used by people.
The fast fashion model uses and pollutes the Earth’s resources at a terrifying rate. It uses a monstrous amount of water, around 93 billion cubic metres per year, and leaves much of it contaminated by toxic chemicals used for dying.1 In fact, 20% of all clean water pollution comes from textile dyeing.3 Because fast fashion is usually produced is in countries with less regulation (what a surprise), the polluted wastewater is often dumped in rivers and seas.
It’s not just the chemicals used in fast fashion that pollute the Earth. An estimated 35% of all microplastic pollution comes not from straws or grocery bags, but from those cheap clothes.3 The majority of fast fashion items are made from synthetic fibres like polyester, nylon, and acrylic, which release microplastics not just when they are thrown away but also every time they are washed.
What is the social impact of fast fashion?
Beyond the environmental impact, fast fashion also treats its workers badly. The clothing industry is one of the most labour intensive sectors in the world, since much of making clothes can’t be automated.4 Every single item in your closet was made a real person.
The fast fashion industry can only offer those cheap prices by using exploitative low-cost labour in countries with minimal labour protections, where workers face unsafe environments, long hours, and severe underpayment.5 Due to the high demand and expectation of quick turnarounds, the garment workers face high workloads with no regard for whether they can keep up. What’s more, numerous studies have found evidence of forced and child labour in the supply chains of many major fast fashion brands.4
The 2013 Rana Plaza factory collapse in Bangladesh, which killed over 1,100 garment workers, highlighted the human cost of cheap clothing.4 This tragic incident is just one example of the systemic exploitation embedded within the fast fashion supply chain and the disregard for health and safety over profit.
Fast fashion values profits over life. It is impossible to sell clothes for low prices without at least severely underpaying garment workers, and at worst endangering their health and lives.
What is Slow Fashion?
Okay, rant over! Let’s talk about the solution to the fast fashion model: Slow Fashion.
Slow fashion is a response to the harmful practices of fast fashion. The term was coined in 2007 by sustainable fashion pioneer Kate Fletcher, inspired by the Slow Food movement, which emphasises thoughtful, local, and sustainable production.6 Just like Slow Food connects people with the origins of what they eat, slow fashion seeks to foster a deeper connection between consumers and the clothing they wear.
At its core, slow fashion is about taking a long term view on how you purchase and treat clothes, and considering the whole lifecycle impact of garments on the environment and on people.
That means choosing quality over quantity, focusing on sustainable production methods, ethical labour practices, and transparency in the supply chain.2 Brands that embrace slow fashion produce in smaller batches, use natural or recycled materials, and ensure that workers are treated fairly throughout the supply chain.
For consumers, slow fashion simply means buying less but invest in better, long-lasting pieces that are made with care and respect for both people and the environment, so we can shift away from fast fashion’s throwaway culture. It’s about shopping with the awareness that every purchase you make has an impact on planet and people.
Many buyers of fast fashion argue that fast fashion is simply all they can afford, and that sustainable clothing brands are simply too expensive. This is why slow fashion is a mindset shift – it’s not about the price per item, but the price per wear. Think about how many clothes you buy in a year. On the same budget, you could buy dozens of fast fashion clothes that you will have to replace every few months, or buy just a handful of good quality pieces that you can wear for years to come.
And slow fashion is about much more than which brands you shop at and how often. A core component is how you treat your clothes: looking after them like the valuable resource they are instead of as disposable items.
The 3 Main Principles of a Slow Fashion Lifestyle
So how can you actually achieve the slow fashion life? Here are the main 3 principles to follow to help you get started with a slow fashion lifestyle.
1. Buy Less
The golden rule of slow fashion is simple: buy fewer clothes. That’s easier said than done in a world built for fast fashion, where discounts, microtrends, and limited-time offers are designed to manipulate people to continuously buying more, so it’s important to recognise those techniques and consciously resist them.
One effective place to start is to implementing a “wait rule”—leave an item on your wish list for at least a week before purchasing. You can also use a checklist, asking yourself ‘Do I need it?’, ‘Do I already own something similar?’, ‘Will I still want this a year from now?’.
Fast fashion thrives on microtrends that push endless wardrobe updates, leading to waste. Instead, invest in timeless pieces that reflect your own style. Shopping for authenticity over trends builds a wardrobe that lasts and feels like you.
2. Use Clothes for Longer
Slow fashion means treating clothes as valuable investments instead of disposable. The most sustainable item is the one you already own, so wear your clothes for as long as possible. Don’t throw out your fast fashion items, but wear them to death before replacing them with better options.
Taking good care of the clothes you already own can make a big difference. Wash at lower temperatures, air-dry, and learn simple sewing skills for small repairs. For bigger fixes, tailors and repair cafés can extend the life of your favourite items. Small adjustments can also make unloved and unworn pieces wearable again.
When you do need something new, choose quality over quantity. Fewer, durable items save money in the long run and align with the philosophy of choosing long-term durability over the short-lived excitement of trends.
3. Buy From Sustainable Companies
When buying new clothes, buy from sustainable and ethical companies. This can involve a bit more research and time, but that’s all part of slowing down and being intentional with your choices.
Materials matter: natural or recycled fibres like organic cotton, hemp, or deadstock are far better than cheap synthetic materials like polyester, which sheds microplastics and stays in the environment for centuries.
Also pay attention to how garment is produced. Ethical brands are transparent about wages, working conditions, and sustainability practices. A lack of information is often a red flag for greenwashing.
Lastly, don’t forget second-hand clothes! Thrifting is affordable, sustainable, and full of unique finds. Local shops or apps like Vinted and Depop can uncover gems while keeping clothes out of landfill.
