At CÉTOILE, sustainability is not a slogan: it's a way of doing things.

We prioritize essential pieces , carefully selected materials , and production designed to last .

On this page, we detail our choices — materials, manufacturing, packaging — simply, with concrete benchmarks and without excessive promises.

CÉTOILE was built around a founding duo :
— mulberry silk , chosen for its lightness and softness, grade 6A and certified OEKO-TEX® Standard 100 ,
— TENCEL™ Lyocell , its plant-based sister, a plant-based fiber appreciated for its breathable comfort and durability, sourced from the TENCEL™ (Lenzing) supply chain.

Together, they outline our vision of a sensitive luxury, designed to last .

In certain seasons, we introduce other fibers that meet this requirement:
— French linen , a local, simple and sustainable fiber, in homage to our origins.
— Organic cashmere , selected in small batches for its softness and longevity.

Certifications and compositions are specified product by product, in complete transparency.

We work with selected partners, chosen for their mastery of materials and the quality of their finishes.

We move forward in small series , by season, with progressive production: controlled quantities, reasoned restocking, to limit overproduction.

The manufacturing process is indicated on the label of each piece.

Our roadmap aims for closer production, where the supply chains and know-how allow, without compromising on quality.

Fabric pouches, sturdy boxes, careful protection: our packaging is designed to be reused , not thrown away.

We limit over-packaging and favour recycled or recyclable materials, when possible, without compromising the protection of the parts.

Packaging choices evolve with the seasons, in a logic of continuous improvement.

We seek a balance between service and simplicity : shipping with care, without going fast at all costs.

We limit unnecessary back-and-forth trips (clear information, advice, suitable packaging) and, when possible, favour more responsible logistics solutions.

We do not claim to have perfect logistics — we choose, we measure, we improve.

We do not claim to be perfect.

We are moving forward, with high standards and transparency.

CÉTOILE is preparing to join 1% for the Planet , to support initiatives in favor of nature and biodiversity.
