Katharine Hamnett doesn't use any exotic animal skin, or hair, fur, angora. But she uses wool, silk, and down feathers to manufacture many of her clothing pieces.
These animal-derived materials are cruel and unethical. They also harm the environment by producing greenhouse gases and wastes. More sustainable alternatives exist.
Katharine Hamnett doesn't show any measurement of its water usage, pollution, greenhouse gas emissions, or waste across the supply chain. She doesn't have any clear sustainability goals, science-based targets, or timeline to improve in the future either.
