Since graduating, Hazem Kais has honed his interest in material work, textures, and fabrication, exploring how fabrics interact with the body and integrating these experiments into garment-making. He has worked on social and sustainable fashion projects involving natural dyes, cultural fashion, and the discovery of natural fibers, including his role as creative director at Civvies, a sustainable fashion brand in Lebanon, and at The Master Peace, where he used wool to create garments and homeware. In 2019, he launched GOODKILL, a label that innovates with materials to create free-form and functional designs. From 2020 to 2024, he taught textile design at ALBA’s School of Fashion, and in 2024, he joined the LAU School of Design to teach fashion design courses.
