As a culture, we throw away a lot of clothes. It’s estimated that a truckload of abandoned textiles is dumped in landfill or incinerated every second, according to the Ellen Macarthur Foundation, a United Nations Environment Programme partner.

Apps have made it easier than ever for people to shop for clothes, and they’re also now at the heart of a movement to buy less, extend the life of what we already own and reduce waste.

Here, fashion-app innovators share how everyone can lighten their environmental impact.

According to Amy Bannerman, eBay’s preloved style director and former fashion director for Cosmopolitan, if you want to lighten your fashion footprint, the first step is simply to know your style.

“Whoever I’m dressing, I always start by asking, ‘Whose style do you really admire?’ It’s shorthand for ‘How do you want to look?’”

Before searching the eBay app for the perfect piece, Bannerman turns to Pinterest. “Mood-boarding using Pinterest is always really good – just save images of people’s style that you like,” she says.

“Life is frantic. If I have an event and I’m short on time, I’ll panic and think I’ve got nothing to wear!” In Bannerman’s experience, an unexpected party is often a trigger for an unnecessary purchase.

Her solution: “Shopping your own wardrobe is the cheapest and the most environmentally friendly.”

With apps such as Save Your Wardrobe, Whering or Storey Wardrobe, you can create a digital inventory of your clothes: photograph an item or take a screenshot from a website to add a piece to your virtual closet.

By cataloguing your clothes you can see exactly what you own and avoid repeat buys (hands up who owns five navy sweaters). Use the apps to mix and match pieces, then save outfits to your favourites.

Bannerman knows that eBay is a great source of fashion finds – it has more than 1.6 billion items up for auction on any given day.

Her team found one seller who had an incredible collection of ’90s vintage Galliano and Dior. “We’ve set a notification so when she adds something new, we know about it,” Bannerman says. To save a seller in the eBay app, go to an item and tap Save Seller.

Bannerman recommends saving your searches. “I’ve got a mental list of things I’m always looking for – like this really rare vintage sheepskin coat that I still haven’t found,” she says. “Every time a listing with ‘shearling’ or ‘sheepskin’ comes to eBay, I get an alert.” To get notifications on searches in the eBay app, select “Save this search” under the search bar.

Circular fashion, a movement within the fashion industry that aims to take a more considered and responsible approach to the manufacture, use and repurposing of clothes in order to maximise longevity and reduce waste, is gaining momentum. Many shoppers are favouring versatility and timelessness over fleeting trends.

Depop – a marketplace for vintage, pre-loved and gently used fashion – has seen this play out first-hand. Since the start of 2023, searches for minimalist clothing surged more than 50 per cent, with buyers clamouring for neutral, modular pieces that can be easily mixed and matched – and that defy fads.

Depop star Ana Aquino had no idea her minimalist clothing designs would resonate when she posted her first product on social media in 2018.

“As you grow up, you change your style pretty often, so I asked, ‘Which styles can customers keep in their closet the longest?’” Her pieces, which feature simple silhouettes in basic colours and fabrics, soon went viral.

Depop enabled her to quickly create a shop for her made-to-order product line, and tap into a thriving community of sustainably minded fashionistas. She’s since built a sizable following for her clothing, which is all crafted using high-quality materials salvaged from unsold pieces, known in the industry as deadstock.

Aquino says that finding an audience for your creations in Depop begins with how you present your storefront. When curating your collection, “think of the app’s social-media style grid layout as a mood board,” she says. “It helps the users look at your store like social media instead of feeling like they’re on a website trying to get sold something.”

Posting pictures in Depop doesn’t require a professional photo shoot – users appreciate seeing pictures that aren’t overly edited, so they know exactly what they’re getting. Aquino says you should be as descriptive as possible about each piece – the app has prompts to get you started. To help buyers find you, go to “enhance your listing – style” and add extra details.

Josephine Philips, founder of London-based tailoring and clothing repairs app SOJO explains how to save money and carbon emissions by mending and lending.

Philips thinks a widespread lack of awareness about tailoring is part of the consumption and waste problem. “So often younger generations haven’t been taught how to sew,” she says. “People don’t really know what can get done, and because of that they throw things in the bin.”

Even if you’re not based in London where SOJO and its team of in-house tailors are available, there are plenty of ways to get your clothes altered. Search Apple Maps or the Yelp app for tailors near you.

Clothing-rental apps, where you can borrow pieces from fellow app users, are an excellent alternative to buying new. “The rise of rental is showing us different ways of engaging with fashion,” says Philips.

And there are more sources for gently used clothes than ever. “Vestiaire Collective is fantastic in the luxury-fashion space,” says Philips. After you purchase an item from a seller, the app verifies the quality before shipping it to you.

Over on eBay, it’s Gen Z shoppers who have been driving the push for pre-loved fashion on the platform, says Bannerman. According to a 2022 research report by the company, shoppers aged 18 to 34 have the highest average percentage of second-hand clothes in their wardrobe (22 per cent), nearly double that of shoppers over 55 (12 per cent).

“With Gen Z, there’s way more willingness to express individuality,” Bannerman says. “They’re less precious, more creative in how they style things.”
