We Are Not Sisters is a sustainable fashion label founded in 2012 and developed as a long-term design and leadership project. The brand brings together ethical production, responsible material choices, and a clear visual identity, positioning fashion as a cultural and social practice rather than a trend-driven product. Lucia Jarosova co-founded the label and has been responsible for its creative direction since its inception, leading the brand independently since 2024. Her role encompasses brand identity, visual communication, collection design concepts, and the coordination of international creative and production teams. The development of the brand is shaped by long-term thinking and continuous refinement of detail (from construction and fit to materials and communication). These improvements are part of a sustainable approach that understands responsibility not as a statement, but as an ongoing process.
