Lock & Co. in London is the oldest hat shop in the world. Our passion for hats is limitless and our knowledge unrivalled. For 345 years, Lock & Co. have worked with the best felts, tweeds, cloth, and cashmere fabrics sourced exclusively from around the world. Drawing from our unique British heritage and craftsmanship, we create both traditional and modern hat designs, with scrupulous attention to quality and fit. Our hat shop was established in 1676, making us the oldest hat shop in the world and the oldest shop in London. Every Lock & Co. hat purchased is carefully and expertly hand-prepared in our London shop by one of our Hatters, before being whisked out of our famous green front door at No. 6, St James’s Street. Two Royal Warrants attest to Lock’s commitment to hat quality that is trusted and respected; everything that you would come to expect from Lock & Co. – the home of hats since 1676.
