What Sustainability Means to Us

What sustainability
means to us
We're realistic — no brand can claim to be 100% sustainable. What we can promise is that we're doing more than most at every single step, and we'll always tell you exactly where we stand.
Fashion is the world's second largest polluter. We can't fix that alone — but we can make sure More Sunday is never part of the problem.
Sustainability at every stage
Most brands only think about sustainability at end of life. We think about it at every stage — from the first thread to the last wash. Tap any stage to see exactly what we do.
The journey from raw material to finished product is where most fashion brands cause the most damage — and where we work the hardest.
- Vertically integrated supply chain — fewer factory-to-factory trips means less fuel, less waste, fewer emissions
- Natural and low-impact dyes — no toxic chemical runoff flowing into waterways and oceans
- No chemical finishes — zero non-iron or non-wrinkle treatments which require harsh chemical washes
- Zero synthetic pesticides — Mulberry silk is naturally produced, unlike cotton which is one of the world's most chemically intensive crops
- OEKO-TEX® STANDARD 100 certified — independently verified free of 100+ harmful substances at every production stage
What happens when you wash your clothes matters more than most people realize. Synthetic fabrics shed microplastics with every wash — natural silk never does.
- Zero microplastic shedding — silk is a natural protein fiber, not a plastic. What goes in your wash stays in your wash
- Wash less often — silk's natural antimicrobial properties keep it fresher longer, reducing water and energy use per wear
- No toxic chemicals released into water systems — unlike polyester and nylon which shed plastic into oceans with every cycle
- Built to last — 19 momme Grade 5A silk maintains its integrity wash after wash, reducing the need and cost to replace
Eventually every piece of clothing reaches the end of its useful life. What happens next is where natural and synthetic fabrics diverge completely.
- 100% biodegradable — natural silk returns to the earth completely, leaving no trace behind
- No forever chemicals — unlike polyester which persists in landfills and oceans for hundreds of years
- Recycled-plastic clothing is well-intentioned but still sheds microplastics in the wash and never fully biodegrades
- Eco-conscious packaging — we minimize single-use plastic so your order's full lifecycle is as clean as the product itself
Why "eco-friendly"
isn't always what it seems
We believe in transparency over marketing. The fashion industry is full of half-truths about sustainability — and consumers deserve the full picture.
We still have areas where we're working to improve. But we'll always tell you where we are, not just where we want to be. That's our commitment to you.
Cotton — the greenwashing myth
Cotton is biodegradable — that much is true. But growing it requires catastrophic amounts of water and synthetic pesticides that flow directly into oceans and soil, often outweighing any end-of-life benefit. Conventional cotton is one of the world's most chemically intensive crops.
Biodegrades ✓ — but the growing process is highly pollutingPolyester — a plastic problem
Polyester is made from crude oil — it is literally plastic clothing. Every wash releases microplastics too small for water treatment to catch. They enter oceans, are eaten by fish, and end up back in our food. Polyester never biodegrades. Clothing made from recycled plastic is better, but still sheds microplastics.
Microplastic shedding ✗ — never biodegrades ✗Mulberry silk — naturally better
No synthetic pesticides in production. No chemical finishes. No microplastic shedding in the wash. Fully biodegradable at end of life. OEKO-TEX certified free of harmful substances. Silk isn't perfect — but it's the most genuinely eco-friendly luxury fabric available today.
The most responsible luxury choice availableWhat we promise
Natural materials only
We will never use synthetic fibers. Every More Sunday piece is made from natural materials that work with your body and the planet — not against them.
Always certified
Every product we make carries OEKO-TEX® STANDARD 100 certification — independently tested and verified free of harmful chemicals at every stage of production.
Clean supply chain
We vertically integrate wherever possible to reduce emissions, use natural and low-impact dyes, and never apply chemical finishes that contaminate waterways.
Honest transparency
We don't claim to be perfect. We share where we are, where we're going, and welcome ideas from our community on how to do better. Always.
Your questions about
sustainable fashion
Is silk more sustainable than cotton?
In most meaningful ways, yes. Cotton biodegrades — but its production demands enormous water and pesticide use that often outweighs that benefit. Mulberry silk is produced without synthetic pesticides, requires far less water, and when OEKO-TEX certified, is free of the harmful dyes that pollute waterways during cotton dyeing and finishing.
Does silk produce microplastics?
No. Microplastic pollution comes exclusively from synthetic fabrics like polyester, nylon, and acrylic — all plastic-based. When washed, they shed microscopic plastic fibers that pass through water treatment and into oceans and food chains. Natural fibers like silk produce no microplastics whatsoever.
Is silk better for the environment than polyester?
Yes, significantly. Polyester is crude oil in fabric form — it never biodegrades, sheds microplastics with every wash, and is produced through an energy-intensive chemical process. Silk is a natural protein fiber: biodegradable, microplastic-free, and produced without synthetic chemicals when properly certified.
What does OEKO-TEX mean for sustainability?
OEKO-TEX® STANDARD 100 certifies that every component of a fabric — threads, dyes, finishes — has been independently tested free of 100+ harmful substances, including formaldehyde, heavy metals, and pesticide residues. For sustainability, it guarantees that the dyeing and finishing processes — where most textile pollution originates — used no toxic chemicals.
Is recycled polyester sustainable?
It's better than virgin polyester — but it still sheds microplastics with every wash and still never biodegrades. Recycled plastic clothing reduces demand for new crude oil but doesn't solve the fundamental problem: plastic doesn't belong next to your skin or in our oceans. Natural fibers remain the more responsible long-term choice.
How can I make my wardrobe more sustainable?
Choose natural fibers over synthetics wherever possible — silk, wool, linen, and organic cotton all biodegrade and produce no microplastics. Look for OEKO-TEX or similar independent certifications. Buy less but better: a high-quality silk piece that lasts years has a lower lifetime footprint than fast fashion replaced seasonally.
