Unmistakably Karen Walker, the Number One has dramatic geometric angles that curve into a soft circular shape that creates our iconic silhouette. Crafted in a glossy black bio-acetate, the chunky black frame is fitted with dark smoke mono lenses for a super chic look. The style is completed with our KW arrowhead pins at the side arms.

These sunglasses are crafted in premium bio-acetate, a more natural version of acetate made with wood pulp that’s cultivated and harvested according to the guidelines of the Forest Stewardship Council (FSC) and a unique vegetable-derived solution that replaces traditional chemical plasticiser. With approximately 68% of its raw materials obtained from natural and renewable sources, these frames are both bio-based and biodegradable.
