Sustainable Fashion: Stop Buying New, Start Repairing

Imagine you're standing in front of your closet, staring at 118 items of clothing. You haven't worn at least 31 of them in the past year. You're thinking about buying a new shirt because you're bored, but you remember that making one cotton t-shirt already used 2,700 litres of fresh water—enough for one person's drinking needs for 2.5 years. You close the closet door. That's the moment sustainable fashion becomes real.

You're not alone in this scenario. The average UK adult owns 118 items, and about 26% haven't been worn for at least a year (WRAP). Fast fashion has trained you to treat clothes as disposable, but the most sustainable garment is the one you already own. The blunt truth: you need to stop buying new and start repairing what you have.

Why Your Closet Is the Problem

Fast fashion delivers constant new styles at rock-bottom prices, and it's wrecking the planet. The fashion sector contributes about 2% of global greenhouse gas emissions, and in the US, 85% of clothing ends up in landfills (EBSCO Research Starters). Textile consumption in the EU crept up from 17 kg per person in 2019 to 19 kg in 2022 (European Parliament). You're buying more and keeping it less.

But here's the thing: the solution isn't to buy "sustainable" new clothes. It's to use what you have longer. In the UK, repairing an item extends its life by an additional 1.3 years, and preloved or vintage clothes are kept for an average of 5.4 years compared to 4 years for new off-the-peg items (WRAP). That's a 35% increase in lifespan just from buying secondhand and fixing things when they break.

The Repair-Not-Replace Mindset

You need to shift your default from "buy" to "fix." When a seam splits or a button pops, don't toss it. Learn basic mending—it's not hard. And if you don't know how, 58% of UK adults are open to using a repair service (WRAP). That's a signal: repair is becoming mainstream, and it's okay to ask for help.

Jeans, for instance, are kept for an average of 4 years in the UK, up from 3 in 2013 (WRAP). That's progress, but you can do better. Non-padded coats and jackets last over 6 years, while underwear is the shortest at 2.6 years (WRAP). So prioritize repairing the items with the longest potential lifespan—outerwear, denim, and knitwear—because that's where you get the most environmental bang for your buck.

The Resale Revolution Is Real

When you genuinely need something new-to-you, buy secondhand first. The global secondhand apparel market is projected to hit $367 billion by 2029, growing at 10% annually (ThredUp Resale Report 2025). In the US, secondhand apparel grew 14% in 2024, its strongest year since 2021 (ThredUp). And 46% of US consumers say that if they can find an item secondhand, they won't buy it new (ThredUp). You should be one of them.

Why? Because secondhand clothes are kept longer, as noted above. Plus, the resale market is booming online—US online resale grew 23% in 2024 and is expected to nearly double to $40 billion by 2029 (ThredUp). So you have no excuse to buy new when you can find quality pieces for less money and less environmental impact.

Compare Your Options: New vs. Secondhand vs. Repair

Look at that table. Repairing is the clear winner for the planet, and secondhand beats new every time. But even better: combine them. When you buy secondhand and then repair it when needed, you're maximizing lifespan and minimizing waste.

What About the Clothes You Don't Wear?

You've got 31 unworn items. Don't just let them sit there. Sell them, donate them, or upcycle them. The resale market is booming, and 94% of US retail executives say their customers already participate in resale (ThredUp). So there's demand for your cast-offs. But be careful with donations: less than half of used garments in the EU are collected for reuse or recycling, and only 1% are recycled into new clothes (European Parliament). So don't assume your bag to the charity shop gets a happy ending.

Instead, consider keeping your clothes longer through repair. If you do decide to part with something, sell it on a platform like ThredUp or Poshmark. That way, you know it's getting a second life, not sitting in a landfill.

The Takeaway

Stop buying new. Start repairing. When you do buy, buy secondhand. It's that simple. The data is clear: repaired clothes last 1.3 years longer, secondhand clothes last 5.4 years vs. 4 years for new, and the fashion industry is a top polluter. Your closet already has enough. Fix it, wear it, and if you must shop, make it preloved.
