Note the very shapely tweed (in Spring!) jacket on the left paired with what could be wool or even gabardine trousers of a slightly different shade. The green is very sharp. Also note the "pinched" front of the green jacket, a short-lived fad that was meant to give the jacket more shape and one that died out with the American entry into the Second World War. A pair of spectator shoes finishes the look.
