In the early 20th century female pilots and other working women often wore trousers. Actresses Marlene Dietrich and Katharine Hepburn were often photographed in trousers from the 1930s. During World War II, women working in industrial work in war service wore their husbands' (suitably altered) trousers, and in the post-war era trousers were still common casual wear for gardening, socialising, and other leisure pursuits.
