Merz b. Schwanen, a German heritage brand, looms its Good Originals products so the garments are seamless except for triangular inserts in the armpit – a game-changer for fit. The label also categorises some cuts by decade, and while the ’50s models work best for my shape, the three-button Henley has the snuggest bicep fit. You do, however, have to figure in a three to five per cent shrinkage with Schwanen’s Good Originals garments, and they are cut small to begin with – so go large.
