World War 2 began in 1939 and ended in 1945. During this time, rationing was introduced which restricted fabrics and leather. Popular toys included dolls, marbles, toy tanks and trains which were often made of wood due to material shortages. For men, suits became simpler with influences from military uniforms while women's fashion emphasized defined waists and accessorizing with scarves, hats and jewelry. Fast food restaurants like drive-ins and hamburger joints became popular alongside soda fountains and snack stands. Entertainment included movies, dancing and listening to popular musicians as radio shows were often broadcast live.
