Two-button jacket, made in London, with a blue worsted cloth from Somerset — a very lightweight, springy travel cloth of merino yarn — and horn buttons from the West Midlands. The SB2 fits true to size, and the most standard 38 in the world — wears S. The body is slim, a standard length, and the waist is gently nipped in. The shoulders are unstructured; the sleeves are an average width.
