Every piece in Heritage begins as the same garment: combed ring-spun cotton, side-seamed, taped neck, no side branding. The regular fit is cut with a slightly boxed shoulder; the relaxed fit drops the shoulder and lengthens the body by four centimetres.
Only the drawing changes. That is deliberate — it means a piece earns its place on the strength of the graphic alone, and it means you already know how the next one will fit.
