8 Best Sustainable Fashion Apps

The second biggest polluting industry in the world is the fashion industry.

Much of the Earth’s water pollution begins in textile factories, nearly 80% of garments end up in landfill and it accounts for nearly 10% of all carbon emissions too!

If we can change our approach to fashion to a more sustainable one, we can save the planet and it’s easy to do with these sustainable fashion apps. 


Depop is a fully social-driven network that allows you to browse one of the world’s largest collections of pre-loved fashion.

They claim nearly 20 million users so that means you’re going to find plenty to suit every fashion taste and whim that you have.

The only downside of Depop is that it can become super addictive due to the bargains you discover there. 


We’ve all bought clothing that we thought would look amazing with the things we already have and when we got it home? It just didn’t and then it lurked at the back of the closet for years before getting thrown out.

Stylebook lets you play dress up with style ideas without spending any money and thus, cuts down on buying the wrong items and fashion waste. 

Good On You

We love the way that Good on You is developing and think it’s the best app of its kind, by far, so far in the marketplace.

It helps you assess the sustainability of brands by giving them rating scores against a number of environmental and ethical criteria and it pulls no punches while it does so.

You’ll find some of our favorite affordable, ethical clothing brands on there.

We think it’s best to assess a brand using Good on You before you spend time falling in love with their clothes. 

Done Good

Buying more clothes isn’t always sustainable but it is often necessary and Done Good wants to help you bridge the gap between buying clothes you love and buying clothes that love the planet.

The app helps you find sustainable brands for the items you’re looking for as well as giving you discount codes for these brands which saves the money as you save the Earth. 

Save Your Wardrobe

The best way to save the planet is to stop throwing out clothing once it’s worn and broken and instead, to repair and refurbish it. 

This is how our grandparents lived, nobody in the post-war generation carelessly threw out that which could be repaired and that’s how Save the Wardrobe wants us to live too.

The app helps you source local repairs and dry cleaning services so that your clothes last longer. 


Shh, don’t tell anyone but, we’ve noticed that there’s a bit of a sexism issue in the slow fashion industry, it’s almost all targeted at women, as though, somehow, men don’t wear clothes too?

Grailed is an attempt to redress this incredible imbalance by encouraging men to go with preloved and preworn items when they’re updating their wardrobe. 

It’s completely free to use and install too.  

30 Wears

This is a great app that we think everyone should be excited about because it operates on a very simple premise – it doesn’t tell you what to wear or how to shop – instead, it encourages you to wear everything at least 30 times before you replace it.

Upload your clothing to the app, tag each item every time that you wear it, complete fun challenges and know that you’re no longer buying clothes just to throw them away.


When you want to turn old clothes into cash or cash into new (but preloved) clothes then Vinted is the ultimate app to make it happen.

You can declutter to start your minimalist wardrobe and shift your excess clothing via Vinted and then you can start to restock from the huge community of similar folk moving their excess clothing.

Kind fashion on a global scale has never been easier. 

Final Thoughts On Sustainable Fashion Apps

*Honorary Mention: While it’s not an app – it’s a browser extension – Finch delivers sustainability to Amazon.
