All Réjeanne collections are designed in Paris by founders Alexandra and Wye, alongside the Réjeanne team — where the very first French period underwear was created in 2017.
“We have always been committed to the highest standards of quality and meticulous attention to every detail, in order to create period underwear collections that are as beautiful as they are high-performing and durable.”
— Alexandra Rychner & Wye Morter
Our period underwear is OEKO-TEX® STANDARD 100 certified (CQ 1254/1 IFTH). This independent certification guarantees that every single component has been rigorously tested against harmful substances, meeting the strict requirements of the OEKO-TEX® STANDARD 100.
Our organic cotton is also the result of highly specialised craftsmanship:
A unique, bespoke construction designed for ultra-fast absorption
An odour-free, organic and breathable fabric
Exceptional softness that makes you forget you’re on your period.

Our patented invisible, leakproof technology was created and developed in France in collaboration with workshops that craft for leading lingerie houses, as well as French textile and patent experts.
1. Moisture-Wicking
A few millimetres of ultra-soft, breathable moisture-wicking fabric made from organic cotton.
2. Absorbent
An ultra-thin fabric that absorbs flow quickly and continuously.
3. Waterproof
A breathable waterproof membrane for leakproof protection for up to 12 hours straight.
We have obtained the OEKO-TEX® STANDARD 100 label (CQ 1254/1 IFTH).
All of our prototypes are entirely developed in France, allowing us to validate the technical performance, quality, and comfort of every product.
Our collections are then crafted in specialised lingerie ateliers in Vietnam, Tunisia, and France, where each garment is carefully made by hand according to the technical expertise and local craftsmanship of each workshop — all in compliance with our OEKO-TEX® STANDARD 100 labelling (CQ 1254/1 IFTH).
