When we think about sustainable basics, we consider them the core items you can wear daily. For example, a classic t-shirt you can pair with anything, a pair of go-to jeans, long-lasting underwear, and a classic sweater or hoodie are all closet staples that make up a streamlined wardrobe.

What makes a sustainable essential “sustainable” is the material it’s made from and the production practices behind the garment.

When choosing eco-friendly essentials, make sure they’re made from sustainable materials and ethical production. For example, sustainable materials for clothing include natural fibers such as organic cotton, linen, hemp, recycled fibers, and wool. These materials are biodegradable and environmentally friendly. They are also durable and long-lasting.

Production practices are just as important as the materials used. Make sure your sustainable basics are ethically made. This means that the workers who made your clothes were paid a fair wage, worked in safe conditions, and had access to fundamental human rights.

The fashion industry is one of the most polluting industries in the world, creating more emissions than air travel and maritime shipping combined.

The rise of fast fashion brands has also led to an increase in clothing consumption and the production of millions of pieces of low-quality garments which fuels overconsumption and the textile waste crisis we’re currently facing.

As eco-conscious consumers, it’s therefore essential we shift our buying habits to choose more responsible materials that don’t harm people or the planet.

If you’re wondering what the worst fast fashion brands are – you can read our full list here.
