Cornwall Jumper: Wool, Navy. Like you borrowed your dad’s cast-off, this knit’s longer in the body, slouchier in the sleeve, made form the softest lambswool and in a shade that nods to storm-lashed seas and cosy pub interiors. For a go-anywhere, do-anything ensemble, pair with straight-leg jeans and loafers. On colder days, throw it over a tailored coat for some instant preppy polish. Designed in London, made in Portugal.
