Scottish Walker Slater may not have a hundred-year-old tradition like some of their competitors but they have something better - large selection of beautiful high-quality jackets and trousers from a wide selection of tweed fabrics (including rightful legends such as Harris tweed) for more than reasonable prices.
Harris tweed is the stuff of legends, by the way. Not many fabrics have their own laws - the Harris Tweed Act 1993. Legally only fabric from virgin wool handwoven in the Outer Hebrides. You may know these islands from the Peter May thrillers. Quality of their tweed is checked by the Harris Tweed Authority.
