30 Wears’ Sustainable Fashion App

Say hello to one of the top slow fashion apps you can have on your smartphone. 

30 Wears is based on the #30WearChallenge, a concept by Olivia Firth from Eco-Age which encourages you to wear all your clothes at least 30 times. 

The challenge is designed to replace overconsumption with a slower approach to fashion. Instead of buying lots of low-quality fast fashion pieces, you choose durable clothing you can see yourself wearing at least 30 times.

You might not think 30 wears is a lot, but the average garment is worn just seven times—and some are never worn.

So, the app allows you to organize your clothes, track each wear, and keep on top of what’s in your closet.

Our Considerations For Choosing The Top Sustainable Fashion Apps

How do we know which apps are moving the needle for sustainable fashion? 

Sustainability doesn’t just just focus on the product or service. We take a look at the entire approach to sustainability across all areas of the business to see how they match up. 

Not every app ticks every box in our criteria but just like clothing, there isn’t a one-size-fits-all. 

Carbon Goals & Achievements:

The fashion industry contributes between 2-8% of global CO2 emissions, so sustainable clothing apps should take active steps to discourage fast fashion and promote ways to keep clothes in circulation.

Cell phone applications also have a digital carbon footprint. On average, they account for ‘0.75 grams of CO2 equivalent.

Brands will need to monitor and improve their app’s efficiency and reduce their overall carbon footprint across their business. 

Supply Chain:

Fast fashion is built on the exploitation of garment workers. We like to see apps hold fashion brands to account by promoting ethical businesses over ones with a murky track record. 

We know it’s not always possible with thrift stores and secondhand marketplaces, and in those cases, we prefer clothes to be kept in circulation rather than sent to landfill anyway. 

Diversity, Equity & Inclusion:

It’s common sense for an app to be intuitive and easy to use. They also get bonus points from us if they add accessibility features, inclusive sizing, and show a diverse range of body types. 

Sustainable fashion is for everyone, after all. 

Closing Thoughts On Ethical & Sustainable Fashion Apps

The rampant consumption of clothes is a symptom of a throwaway culture. 

We buy more clothes than ever before and wear them less—amassing 92 million tons of clothing waste every year. 

Discarded clothes are burned or dumped in landfills where they sit and rot for over 50 years, meanwhile releasing CO2 and other greenhouse gases into the environment. 

Sustainable clothing apps aren’t just another fashion accessory. 

They’re tools that empower consumers to not only shop for clothes more consciously, but to keep the clothes we buy in the circular economy for longer. 

Plus, they’re free to download and use, so what are you waiting for?

And while you’re waiting for your download, be sure to give this article a quick share so more people can APPly the principles of slow fashion right from their pocket.
