The principal change in menswear in the 1960s was in the weight of the fabric used. The choice of materials and the method of manufacture produced a suit that, because it was lighter in weight, had a totally different look, with a line that was closer to the natural shape of the body, causing men to look at their figures more critically. The spread of jeans served to accelerate a radical change in the male wardrobe. Young men grew their hair down to their collars and added a touch of color, and even floral motifs, to their shirts. The polo neck never succeeded in replacing the tie, but the adoption of the workman's jacket in rough corduroy, and especially the mao jacket proved to be more than simply a political statement. A few futuristic rumblings were set off by Pierre Cardin and Andre Courrèges, but the three-piece suit still survived intact.
