But in reality, sustainability is not just about what something is made from—it is about how long it lasts, how it is made, and what happens to it over time.

A garment worn and valued for years will always have a different impact than one designed to be replaced quickly, regardless of the fabric it began with.

So rather than treating ethics and sustainability as fixed ideas, it helps to break them down into how they actually function in practice.

WHAT SUSTAINABILITY ACTUALLY MEANS

In fashion, sustainability is often used as a marketing term, but in practice it refers to a combination of factors:

• environmental impact of materials
• water, energy, and chemical use in production
• waste generated during design and manufacturing
• durability and lifespan of garments
• and how clothing is used, repaired, or discarded over time

It is not a single decision, but a series of connected ones across the life of a garment.

MATERIALS: WHERE SUSTAINABILITY STARTS (BUT DOESN’T END)

Materials are often the first point of focus in sustainability discussions, but they are only one part of the picture.

Different fibres carry different environmental profiles:

• natural fibres such as cotton or wool
• synthetic fibres such as polyester and nylon
• blended fabrics that combine properties and trade-offs
• organic, recycled, or repurposed textiles

Even within “natural” or “synthetic” categories, the environmental impact can vary depending on how the fibre is grown, processed, dyed, and finished.

This means fabric choice is rarely a simple good-versus-bad decision. It is more about understanding how each material behaves across its lifecycle.

PRODUCTION: WHAT HAPPENS BEHIND THE FABRIC

Sustainability is also shaped significantly by how garments are made.

Key considerations include:

• how much material waste is produced during cutting and construction
• whether patterns are designed efficiently to reduce offcuts
• whether existing materials are reused or repurposed
• and how much energy and water is required in production processes

Approaches such as upcycling, deadstock usage, and efficient pattern layout can significantly change the environmental footprint of a garment, regardless of the original fabric choice.

PRODUCT LIFECYCLE: WHAT HAPPENS AFTER CREATION

One of the most important parts of sustainability is often overlooked: what happens after a garment is made.

This includes:

• how long it is designed to last
• whether it can be repaired, altered, or resized
• how well it maintains its structure and appearance over time
• and what happens to it at the end of its usable life

A garment that is worn repeatedly, repaired, and adapted over time will generally have a lower environmental impact than one that is replaced frequently.

Longevity is often one of the most overlooked aspects of sustainability.

PRACTICE-BASED REFLECTION 

In my own work with textiles and design, sustainability is rarely a theoretical choice—it is a practical consideration at every stage of development.

Material selection is often influenced not only by environmental considerations, but also by availability, durability, cost, and how the fabric behaves in the final garment.

There are also situations where more sustainable options may not be accessible within the constraints of a project, which means decisions often involve balancing ideal outcomes with realistic ones.

This is where sustainability becomes less about perfection, and more about intention and awareness in the design process.

TRADE-OFFS IN SUSTAINABILITY

Sustainability in fashion is not without compromise.

More environmentally responsible materials may be more expensive or harder to source. Natural fibres may have higher water usage depending on how they are grown. Synthetic fibres may offer durability but present long-term environmental challenges.

These trade-offs mean sustainability is rarely a clear or absolute choice, but rather a set of considerations that shift depending on context.

REFLECTION

Sustainability is often presented as something that can be achieved through the “right” materials or decisions.

In practice, it is better understood as an ongoing process of evaluating impact, making adjustments, and working within real-world constraints.

It is not a fixed outcome, but a continuous design responsibility.

So perhaps the question is not simply what makes a fabric sustainable.

But how we design garments that remain valuable, usable, and meaningful long after they are made.
