"Op art works are abstract, with many of the better known pieces made only in black and white". When the viewer looks at them, the impression is given of movement, hidden images, flashing and vibration, patterns or alternatively, of swelling or wraping. (Wikipedia Op art). In the 1960's op art had a big influence on fashion. These prints were showing up on everything from paper, to advertisements to textiles. The most well known print and piece during this time was the Yves Saint Laurent "Mondrian" shift dress. The strong lines and bold colors of the dress. Other designers to be inspired by Op art, were Marc Jacobs, Jonathan Saunders and Tory Burch. Their Spring 2009 collections featured prints that were represented of op art, the optical illusion of moving space. Beautiful colors and abstract shapes were also used as well with the prints and textiles of the collection. All inspirations of the Op art movement.
