MaisonCléo is a sustainable French fashion brand founded by mother-daughter duo Marie and Nathalie Dewet (nicknamed Cléo) in 2017. Born from Marie's frustration with finding locally-made, natural fiber clothing at accessible prices, the brand started when she asked her professional seamstress mother to create handmade silk tops. What began as personal Instagram posts quickly gained attention from fashion influencers like Leandra Medine and Emily Ratajkowski. The brand operates on a made-to-order model, exclusively using deadstock fabrics from French couture houses and factories, ensuring zero waste. Each piece is handcrafted in their North of France atelier, with full transparency regarding fabric costs and production time. MaisonCléo follows no fashion calendar or seasonal collections, instead creating designs based on available materials. The brand specializes in feminine blouses and dresses made from natural materials like silk, cotton, and linen, embodying the family's multi-generational seamstress heritage and commitment to slow, authentic fashion.
