After decades as a textile and apparel consultant, I made a deliberate shift: I joined Grey Matter Concepts. Why? Because this isn’t just another brand riding the sustainability wave. It's building a better business model from the ground up. Grey Matter focuses on the basics: socks, underwear, loungewear. But behind that simplicity is an ambitious, transparent, and principled approach to sourcing, production, and impact. What drew me in was the team’s commitment -- especially from founder Rachel Landau -- to operational integrity over greenwashing. From full supply chain traceability to vertical integration in India, Grey Matter is scaling with intention. I joined to help grow a resilient, responsible supply chain and support a company asking the right questions about circularity, quality, and affordability. And answering those questions with real solutions. This industry doesn’t change easily. But Grey Matter isn’t trying to be loud. It’s trying to be honest. And in today’s apparel world, that’s revolutionary. That’s why I’m here. Please have a read. #apparel #sustainbility #strategy #sourcing #opportunity #creativity #manufacturing #honesty GREY MATTER CONCEPTS

📢 The Woman Redefining Men’s Basics In honor of Women’s Month, we’re launching our Women Who Matter series—celebrating the vision, leadership, and impact of women shaping the future of fashion. Grey Matter Concepts started with a bold idea—create high-quality, performance-driven essentials while prioritizing innovation, sustainability, and smart design. Our founder, Rachel Landau, turned that vision into reality, leading with passion, industry expertise, and a commitment to excellence. From redefining men’s underwear to building strategic global partnerships, we have grown into a powerhouse in the apparel industry—all while staying true to our core values of quality, function, and sustainability. India’s potential as a key player in global fashion sourcing is a game-changer. As Rachel highlights, India’s pro-business attitude, sustainable practices, and reliable supply chains make it an increasingly attractive partner. Now is the time to build meaningful partnerships with India—driven by reliability, efficiency, and sustainability. 📖 Read more here: Why India Matters for Global Fashion Sourcing This is more than a business—it’s a mission.
