Sustainable clothing is designed and manufactured to minimize its impact on the environment. Sustainable fashion is different from conventional clothing because it reduces the number of resources used and produces less pollution during production. Sustainable clothing should also be high-quality and focus on the longevity of the clothing.

Eco-friendly clothing is often made from recycled or natural materials, such as organic cotton, wool, bamboo, and hemp. It is also often made using production techniques that use less energy and cause less waste.

Unfortunately, workers across the fashion industry are often exploited, working long hours with little pay. Sustainable clothing should also be produced ethically, ensuring fair wages and safe working conditions for those involved in the production process.

Researching the company’s practices is one of the best ways to determine if a fashion brand is sustainable. Many companies have a website sustainability page outlining their commitment to producing sustainable clothing.

Look for transparent information about their use of natural, organic, or recycled materials and their commitment to ethical manufacturing processes. If a brand is being shady about where it’s clothing is produced, that’s a big red flag the brand isn’t sustainable.

Another great way to check if a brand is ethical or sustainable is to look for certifications to ensure their claims are valid. Certification such as:

  • GOTS-organic certification proves that their material is organic.
  • WRAP, Fair Trade, and Fair Wear – These certifications show that factories ensure safe working conditions.
  • Oeko-tex – A certificate that ensures clothing doesn’t contain harmful chemicals.

Additionally, it is essential to look at the quality of the clothes – fast fashion is a massive problem because brands are notorious for creating low-quality clothing you’ll need to throw out after the first wear. Discarding clothes because they’re poor quality is causing a huge textile waste problem. Instead, choose high-quality pieces, and check reviews.
