Versatile, timeless, and classic — a pair of blue denim jeans is an absolute wardrobe staple. 

You can match a classic pair of blue denim jeans with any top to complete your outfit and you can wear it just about anywhere. Come to think of it; it’s probably the one wardrobe staple that’s flattering and universally fitting on all body types, shapes, and sizes!   

While denim jeans are a mainstay in everyone’s closet, not all of them are sustainably made. 

In case you’re not aware, the production of fast fashion denim can be quite problematic: 


Is Zara sustainable?

Even mainstream fashion retailers were found guilty of unsustainable denim production.  

Spanish fashion brand Zara might have the latest on-trend denim jeans, but they have a reputation for having unsustainable product turnover rates. In just 13 days, customers can get a hold of a new line of denim jeans fresh from the runway, and this ‘warp-like’ speed of consumption is harmful to both workers and the planet. 

What are the worst fast fashion brands?

Fast fashion denim might be trendy and cheap, but it comes at a high cost. 

Forever 21’s jeans might be good-looking, but they use environmentally degrading petrol-based textiles for their products. The brand also refused to sign the Bangladesh Accord, which protects the safety rights of garment workers. Fashion retailer brands like Boohoo and Missguided were also described as the ‘worst’ when it comes to environmental impact and labour conditions.

What are the most sustainable fashion brands?

Thankfully, eco-conscious brands are going against the perils of fast fashion. Sustainable fashion brands include Patagonia, which uses recycled cotton for their outdoor wear, and Boden, which upholds ethical practices at every step of their supply chain. While these brands may be ethical, they do not specialize in sustainable denim.
