Even though they are often used together, the term fashion differs from clothes and costume, where the first describes the material and technical garment, whereas the second has been relegated to special senses like fancy-dress or masquerade wear. Fashion instead describes the social and temporal system that "activates" dress as a social signifier in a certain time and context. Philosopher Georgio Agamben connects fashion to the current intensity of the qualitative moment, to the temporal aspect the Greek called kairos, whereas clothes belong to the quantitative, to what the Greek called chronos.
Furthermore, political revolution also made much impact on the fashion trend. For example, during the 1960s the economy had become wealthier, divorce rate was increasing and government approved the birth control pill. This revolution inspired younger generation to rebellion. In 1964, the leg-baring miniskirt has become a major fashion trend of the 1960s. Given that fashion designers began to experiment with the shapes of garment, loose sleeveless, micro-minis, flared skirts, and trumpet sleeves. In this case, mini-skirt trend became an icon of the 1960s.
