Fashion in the 1970s grew increasingly individualistic. The ethnic look flourished. Colors became bolder and brighter, and loose, baggy clothes were introduced. Women's skirts gradually lengthened and became more flowing, while men's dress incorporated frilled or patterned shirts, wide ties, and embroidered waistcoats. Flared pants were worn by both sexes.
