Just as Fashion Week is ending, a portrait (above, left) of the influential Parisian couturier Jacques Fath (1912-54) is being offered this month by Britain’s Nicholas Bagshawe Fine Art. Fath was considered one of the three dominant influences on postwar haute couture, along with Christian Dior and Pierre Balmain.
