You can't mention Pop Art and not mention Andy Warhol. But Pop Art was an art movement and style that had its origins in England in the 1950's, and made its way to the United States during the 1960's. Pop artists focused attention upon familiar images of the popular culture such as billboards, comic strips, magazine advertisements, and supermarket products.
From a surface level, Pop Art often came across as shallow and superficial. But the original Pop Art fashion movement was both political, in that it challenged the domination of couture and bourgeois status dressing, and an artistic reaction to abstract art and design, with the satirical and ironic use of advertising and of representational everyday objects.
Early Pop Art in Britain was a matter of ideas fueled by American popular culture viewed from afar, while the America artists were inspired by the experiences of living within that culture. Pop Art therefore coincided with the youth and pop music phenomenon of the 1960's, and became very much a part of the image of fashionable, 'swinging' London.
Some freelance designers took their inspiration from sources of contemporary art and graphics like Andy Warhol's Pop Art images. Warhol influenced fashion, and Yves Saint Laurent certainly went down the pop art road with his Mondrian dress and the black and white block sheaths he introduced in the early 1960s. Brightly colored large-scale geometric repeats were favorites for both dress and furnishing fabrics. And today, Pop Art still influences designers and runway couture.
