Responsible by Design
Sustainability isn’t a label we wear — it’s a system of small, honest choices made daily across our fabrics, supply chain, packaging, and the way we design for longevity.
Better for You, Better for the Planet
The fashion industry is the world’s second-largest polluter. We refuse to be part of the problem — which is why every Muse Casey piece is made from natural, traceable materials and built to be worn for years, not seasons.
We publish our fabric sources and partner ateliers openly, because we believe accountability beats marketing.
How We Do It
Natural Materials
European flax linen, GOTS-certified organic cotton & traceable recycled fibers — nothing synthetic unless it truly serves the garment.
Transparent Chain
Every atelier is audited for fair wages and safe conditions. We publish where fibers are grown and where garments are made.
Plastic-Free
Recycled paper mailers, kraft tissue, and compostable bags. Carbon-conscious shipping partners on every route.
Made to Last
Reinforced seams, pre-shrunk natural fabrics, and timeless cuts — designed to be worn for years, not seasons.
What We’re Made Of
European Flax Linen
Grown in Normandy, France. Flax requires 45% less water than conventional cotton and needs almost no irrigation. Pre-washed for softness, it gets better with every wash.
GOTS Organic Cotton
Certified organic cotton grown without synthetic pesticides or GMOs. Gentle on your skin and on the soil, harvested by audited farming cooperatives.
Recycled & Traceable Fibers
Where a natural fiber can’t do the job alone, we use OEKO-TEX-certified recycled materials — giving textile waste a second life.
From Fiber to Finished Garment
Every step is documented and independently audited. If we can’t trace it, we don’t sell it.
- Partner ateliers audited for fair wages & safe working conditions
- Low-impact, OEKO-TEX-certified dyes and finishing
- Minimal-waste pattern cutting — offcuts are recycled into accessories
- Independent third-party inspections on every production batch
Zero Plastic, Zero Waste
Your order arrives plastic-free, in packaging you can reuse or recycle.
- Recycled & recyclable kraft paper mailers
- Compostable garment bags instead of plastic polybags
- FSC-certified tissue and card inserts
- Carbon-conscious courier selection at checkout
Our 2027 Targets
We publish our goals publicly — and we’ll report on them publicly too.
