Space age fashion first appeared in the late 1950s, and developed further in the 1960s. It was heavily influenced by the Space Race of the Cold War; the futuristic design style was inspired by space exploration. Designers often emphasized the energy and technology advancements of the Cold War era in their work. The space age look was defined by boxy shapes, thigh length hemlines and bold accessories. Synthetic material was also popular with space age fashion designers. After the Second World War, fabrics like nylon, corfam, orlon, terylene, lurex and spandex were promoted as cheap, easy to dry, and wrinkle-free. The synthetic fabrics of the 1960s allowed space age fashion designers to design garments with bold shapes and a plastic texture. Non-cloth material, such as polyester and PVC, became popular in clothing and accessories as well.
