At its core, circular fashion aims to decouple economic growth from the use of natural resources and raw materials. It is often presented as an antidote to the wasteful, polluting practices of fast fashion.

But what exactly is circular fashion? What are the key principles and practices that define this new paradigm for the textile industry? In this comprehensive guide, we will examine what circular fashion entails, from sustainable design and production methods to innovative business models. Core concepts like "reduce, reuse, recycle" will be explored and contextualized for the apparel industry. Leading examples and innovative solutions driving this systemic shift will be analyzed as well.

Defining circular fashion is an important first step in catalyzing much-needed changes in the apparel sector. This article provides an in-depth look at what circular fashion means in theory and practice, setting the stage for the transformative solutions needed to create a truly sustainable fashion industry. The time has come to reimagine the broken fast fashion model and move towards a circular future for textiles and clothing.

Defining Circular Fashion

The concept of circular fashion represents a dramatic shift from the standard linear "take-make-dispose" model that has dominated the apparel industry. Circular fashion aims to decouple economic activity from the consumption of finite resources through innovative design, production, and business models. But what are the key principles and practices that comprise circular fashion?

Reduce, Reuse, Recycle
The core philosophy underpinning circular fashion systems is encapsulated in the “3Rs”: reduce, reuse, recycle. This involves:

Reducing the overall material inputs, waste, energy and pollution across the supply chain. Examples include using zero-waste pattern cutting techniques and minimalist packaging.

Reusing garments and materials multiple times through designing for durability, repair, refurbishment and re-commerce. Clothing rentals and resale platforms enable extended product lifecycles.

Recycling old clothing and textiles back into new fabrics and yarns through mechanical and chemical processes. Emerging technologies like fibre-to-fibre recycling help retain material quality.

Closed-Loop Systems
A key goal of the circular model is to capture all textiles at their end-of-use to feed back into the manufacturing loop and avoid any material ending up as waste. This relies on take-back programs, collection systems and reuse networks to recover clothing and recirculate fabrics and fibres.

Slower Material Loops
Circular systems emphasize slowing material loops by designing durable garments that can be worn for longer vs cheap fast fashion. Higher utilization through rentals and resale further prolongs product lifetimes.

Renewable Inputs
Transitioning to renewable, sustainably-sourced raw materials is a priority, including organic cotton, recycled PET and man-made cellulosics. Investments in agriculture help improve traceability and environmental practices.

Sustainable Practices in Textile Production

Implementing circularity in the fashion industry requires transforming production methods and supply chains to be more sustainable. This chapter explores key practices that are enabling a shift to closed-loop and environmentally regenerative models of textile manufacturing.

Use of Sustainable Materials

  • Organic Cotton: Cotton grown without toxic pesticides and synthetic fertilizers has a lower environmental impact. Brands like Patagonia use 100% organic cotton.
  • Recycled Polyester: PET plastic bottles can be recycled into polyester fiber for clothing. Adidas uses recycled polyester to make over 50% of its polyester apparel.
  • Tencel: Made from sustainably-sourced wood pulp, Tencel lyocell fiber is biodegradable and produced in a closed-loop process. Stella McCartney and Levi’s use Tencel in select designs.
  • Upcycled Materials: Waste fabrics and used garments are transformed into new textiles, diverting waste and reducing processing impacts. Brands like Evrnu and Renewcell specialize in textile upcycling.

Closed-Loop Manufacturing

  • Zero Liquid Discharge: Closed-loop water systems filter and recycle water used in textile dyeing and treatment, reducing pollution and waste. Companies like Tejidos Royo implement this.
  • Renewable Energy: On-site solar and wind energy helps factories power operations through clean sources vs fossil fuels. Adidas and H&M aim to fully transition to renewable electricity.
  • Take-Back Programs: Brands such as H&M and Eileen Fisher have implemented initiatives to collect used clothing from customers to recycle into new products.

New Enabling Technologies

  • Blockchain Tracking: Digital product passports on blockchain enable full transparency and traceability from raw materials to finished garment. Startups like Provenance are spearheading this.
  • Chemical Recycling: Emerging processes like hydrothermal recycling allow polyester and nylon garments to be broken down into base chemicals for polymer remanufacturing. Worn Again and Evrnu are innovators.
    Digital ID Tags: Radio frequency identification (RFID) tags and smart barcodes attached to clothing can store data and track items across supply chains and use cycles. C
  • ompanies like Avery Dennison provide these technologies.

The shift towards circularity in apparel manufacturing is being enabled by impact-driven brands embracing innovative new materials, processes, and technologies. However, scaling sustainable production remains an industry-wide challenge requiring transformation across all levels of the value chain. But the solutions explored in this chapter demonstrate the tangible pathways for creating closed-loop, waste-free fashion supply chains.

Circular Business Models

While sustainable design and manufacturing practices are central to circular fashion, new business models are also critical for scaling circularity. Innovative companies are pioneering alternative approaches that keep clothing in use longer and shift the basis of growth from production volumes to utilization rates.

Clothing Rentals

Rental models provide access to clothing through subscriptions or short-term loans. By extending use across multiple wearers, the overall production of new garments reduces. Rental platforms include:

  • Rent the Runway - an online rental service offering designer fashion for special occasions or temporary use.
  • Nuw - a Netflix-style monthly subscription allowing women to swap items from a rotating wardrobe.
  • Designerex - a peer-to-peer rental marketplace enabling users to lend and borrow designer fashion.

Resale and Recommerce

The resale market turns closets into stockrooms to extract more value from clothing via reuse. Digital platforms like The RealReal and ThredUp have fueled growth in secondhand and vintage fashion. Brands are also launching their own resale shops, including Patagonia, Levi's, and Eileen Fisher.

Upcycling and Reconstruction

Upcycling repurposes discarded materials and clothing into new designs. Brands like Christopher Raeburn reconstruct military uniforms into outerwear while Nudie Jeans repairs damaged denim into upcycled lines. DIY fashion and customization also encourage unique remakes of existing garments.


Some brands are piloting performance-based models where customers pay for the service of clothing rather than owning the product. Dutch brand Mud Jeans leases jeans for a monthly fee while Filippa K offers subscriptions for its front-runner garments. These service models incentivize companies to design durable products that retain value over longer lifetimes.

The rise of access-based, peer-to-peer, and hybrid business models creates opportunities to decouple revenue from the extraction of natural resources. Prioritizing utilization over ownership is allowing forward-thinking brands to profit while reducing textile waste - aligning commercial success with sustainability.
