FAQs

Find answers to the most common questions here.

What is sustainable denim?

Sustainable denim is produced using materials and processes that are less resource-intensive, reduce waste, reduce emissions, use less chemicals, and promote water stewardship. Sustainable denim is durable and crafted to be worn for years.

Additionally, sustainable denim is produced in a social fair and transparent manner.

Why should I care?

Conventional denim production has significant environmental and ethical impacts that are often overlooked. The process typically involves:

  1. High Water Usage: It can take nearly 1,000 gallons of water to produce a single pair of jeans, contributing to water scarcity in vulnerable regions.
  2. Chemical Pollution: Traditional denim manufacturing relies on harmful chemicals like synthetic dyes and pesticides, which can contaminate water sources and harm local ecosystems.
  3. Excessive Waste: Fast fashion drives overproduction and waste, with millions of unsold or discarded garments ending up in landfills each year.
  4. Unethical Labor Practices: Many conventional denim brands rely on cheap labor, often under poor working conditions with low wages and minimal protections for workers.

By choosing truly sustainable denim, you’re helping to combat these issues. Our curated selection supports brands that prioritize eco-friendly materials, ethical labor practices, and water-saving technologies, all without sacrificing style or quality. Your choices matter, and together we can make a difference in the fashion industry and the planet.


We don't want to demonize jeans, as we love them just as much as you do. Rather, we aim to promote awareness and help individuals make more conscious decisions that benefit the planet.  

Is thrifting more sustainable? 

Buying less and shopping second-hand is certainly more sustainable than buying new jeans. However, if you are in need of a fresh new pair of jeans, choosing jeans that are less resource intensive and that have less impact on the environment. That's where we come into help.

What is Proper's criteria for selecting a denim brand? 

We believe in full transparency. That’s why every brand in our marketplace meets strict criteria for sustainability, from the sourcing of materials to the manufacturing process.

  • Material Health: Knowing the chemical ingredient of every material in a product and optimizing towards safer materials
  • Material Reutilization: Designing products made with materials that come from and can safely return to nature or industry

  • Water stewardship: Regarding clean water as a precious resource and an essential human right
