The hidden plastics in our wardrobes
When people think about sustainable clothing, they often focus on the main fabric.
Organic cotton.
Linen.
Wool.
Silk.
These natural fibres are widely recognised as more environmentally responsible alternatives to synthetic fabrics such as polyester or nylon.
But there is a lesser-known issue within the fashion industry: plastic components hidden within otherwise natural garments.
Even clothing made from natural fibres often contains plastic in the small details, things like:
- Buttons
- Elastic
- Sewing thread
- Labels
- Zips
- Interfacing
These components may seem insignificant, but they can dramatically affect the environmental impact of a garment.
Why plastic components are a problem
Most plastic clothing components are made from petroleum-based materials such as polyester or nylon.
While they are inexpensive and easy for manufacturers to source, they create long-term environmental problems.
Plastic components:
• do not biodegrade naturally
• can remain in landfill for hundreds of years
• are made from fossil fuels
• can shed microplastics into the environment
This means that even if a garment is made from organic cotton or linen, the plastic elements can prevent it from fully breaking down at the end of its life.
In effect, these small plastic pieces quietly undermine the sustainability of the entire garment.
A real example: when plastic buttons fail
Recently I experienced this problem firsthand.
I bought a 100% organic cotton shirt, believing it aligned perfectly with my commitment to natural fibre clothing.
But the first time I ironed it, the plastic buttons melted.
The fabric itself was beautiful and durable, but the plastic components were not.
Rather than discarding the shirt, I replaced the buttons with biodegradable Corozo buttons made from tagua nuts.

When a Plastic Button Undermines a Sustainable Shirt
This small repair not only restored the garment but also made it far more environmentally aligned.
Natural alternatives to plastic garment components
Fortunately, there are many beautiful natural alternatives to plastic components.
For example:
Corozo buttons
Made from tagua nuts, often called vegetable ivory.
Wood buttons
Biodegradable and durable when responsibly sourced.
Metal buttons
Highly recyclable and extremely long lasting.
Natural rubber elastic
A biodegradable alternative to synthetic elastics.
Cotton thread
Instead of polyester thread, which is widely used in garment manufacturing.
When designers consider these materials from the beginning, garments can become fully biodegradable or far easier to recycle.
Designing clothing without hidden plastics
At Beautiful Benevolence, avoiding hidden plastics is one of the guiding principles behind every design.
Many accessories, particularly hair ties and scrunchies, contain synthetic elastic and polyester thread that can take decades to break down.
We chose to approach things differently.
Our SAGE biodegradable scrunchie is made using organic cotton fabric and a natural rubber stretch core instead of petroleum-based elastic.
This means it can break down naturally over time rather than lingering as plastic waste.
It’s a small accessory, but it represents a much bigger philosophy: every material choice matters.
Why small design decisions shape sustainable fashion
Sustainability in clothing is not determined by a single material.
It is the sum of every design decision.
Fabric
Buttons
Thread
Elastic
Labels
Each choice influences how a garment is produced, worn, and eventually returned to the earth.
When these decisions are made thoughtfully, clothing can last longer, repair more easily, and leave far less behind when its life eventually ends.
A more thoughtful approach to fashion
The future of sustainable fashion will not only depend on innovative fabrics.
It will depend on designers and consumers paying attention to the details that often go unnoticed.
By choosing natural materials, repairing garments, and supporting brands that avoid hidden plastics, we can all contribute to wardrobes that are lighter on the planet.
Because sometimes the smallest components, like a button or a piece of elastic, can make the biggest difference.
