France
Le Slip Français makes underwear and basics in France using organic cotton and ethical manufacturing. Their essentials are produced domestically with minimal environmental impact, emphasizing timeless design over fast fashion trends.
Le Slip Français could strengthen its supply chain transparency by publishing a detailed factory list and farm-tracing documentation. While the brand's longevity credentials are strong, more formal third-party certifications (beyond OEKO-TEX) would reinforce its sustainability positioning. The repair program, though available, could be promoted more visibly as a core pillar of the brand's durability promise.
Every brand on Oras is independently researched across five pillars: material quality, construction and craftsmanship, longevity and repairability, sustainability and ethics, and design philosophy. We use a consistent framework so you can compare brands meaningfully.
Oras does not sell products directly. We connect you to the brand's own site. We may earn a small affiliate commission, but this never influences our research or which brands we feature.
